Hi all,

I messed up this question recently so just want to clarify and try again. We want to know the cortical gray matter surface area of our subjects but are unclear about how to get this info.

?.aparc.stats reports:

Measure Cortex, WhiteSurfArea, White Surface Total Area, XXXX, mm^2

How about the gray matter?

Thanks, Will

Hi Will,

I think lh.ribbon.mgz and lh.ribbon.mgz contain the volumes of the left and right cortical gray matter. You can extract a list of vectors on a 1 mm grid which fills these regions using mri_cor2label and count the vectors.

Regards,

Don

Hi Will,

I use the following commands to get surface area from the pial surface:

In the subject label dir:

mris_anatomical_stats -mgz -cortex ../label/lh.cortex.label -f ../stats/lh.APARC.PIAL.stats -b -a ../label/lh.aparc.annot -c ../label/aparc.annot.ctab SUBJ lh pial

mris_anatomical_stats -mgz -cortex ../label/rh.cortex.label -f ../stats/rh.APARC.PIAL.stats -b -a ../label/rh.aparc.annot -c ../label/aparc.annot.ctab SUBJ rh pial

Then run aparcstats2table using APARC.PIAL instead of aparc (only because I called this new parcellation aparc.pial)

To get the total surface area of each hemisphere I use:

In the subject stats dir:

mris_anatomical_stats -l ../label/lh.cortex.label -f lh.TOTAL_PIAL.stats -b SUBJ lh pial

mris_anatomical_stats -l ../label/rh.cortex.label -f rh.TOTAL_PIAL.stats -b SUBJ rh pial

Then run aparcstats2table using TOTAL_PIAL instead of aparc (again, only because I called this new parcellation total_pial. You may call it whatever you'd like)

Just remeber to leave the specified dirs when creating the tables. If you dont't I think they will be created in the current dir.

I use FS 5.0.

Is this what you want?

Best, Andreia

Thanks very much Andreia, yes this does look like what I want. I haven't had a chance to test it yet but it does indeed appear to answer my question. Thanks to those that have offered answers, to clarify, I did indeed mean the surface area of the pial surface rather than the white/grey boundary.

Thanks Andreia, this does appear to have worked. Please forgive my ignorance but I do just want to double check two things;

1) The first commands you have given provide the stats for the two hemispheres of the cerebral cortex only based on the pial surface, whereas the second set of commands provide the pial boundary stats for the whole brain rather than just cortex?

2) The surface area value that I am looking for (grey matter surface area at the grey/pial boundary) is listed in the new stats table next to: *# Measure Cortex, WhiteSurfArea, White Surface Total Area,* ?

Thanks again, Will

Hi Will,

Just to clarify, what version of FS are you using? I think it might not be 5.0 and I don't know if everything aplies if we are using different versions.

1) Yes, it is only based on the pial surface (and these command lines are for the aparc, DK altas). The second set provides the surface area for each hemisphere without including, for example, the pial surface that you see in the hippocampus which is not accurate and one should not care about. In the end, the second set gives you the sum of the areas in aparc, thus, you can just make a sum of that parcellation if you want. I just realized that.

2) No. In the new stats file, the value that you want is at the bottom:

# ColHeaders StructName NumVert SURFAREA GrayVol ThickAvg ThickStd MeanCurv GausCurv FoldInd CurvInd

And when running aparcstats2table that's the value you should get in the table. I think that # MEASURE CORTEX, WHITESURFAREA, WHITE SURFACE TOTAL AREA may be including more stuff since it is bigger.

If what you want is only the total hemisphere surface area you only need to run the second set of commands. If you want the area of each DK altas parcellation then run the first set and then simply add them to get total hemisphere surface area.

Someone from Freesurfer staff will correct me if I'm wrong. (Please) I'm Ccing Doug since he was replying to your previous emails.

Let's wait for their feedback.

We want to know the cortical gray matter surface area of our subjects but are unclear about how to get this info. ?.aparc.stats reports: Measure Cortex, WhiteSurfArea, White Surface Total Area, XXXX, mm^2 How about the gray matter? Thanks, Will

Sure. We'd like to know how to find the surface area of the cortical grey matter from the pial surface. So specifically, what is the surface area of the pial/grey matter boundary of the cortex for each hemisphere?

We're using Freesurfer v5.3 on Centos 6.

Thanks, Will Brown

Ok. Then, I'm not sure if everything is correct with the command lines since I use 5.0.

        Hi Will,

        Just to clarify, what version of FS are you using? I
        think it might not be 5.0 and I don't know if
        everything aplies if we are using different
        versions.


        1) Yes, it is only based on the pial surface (and
        these command lines are for the aparc, DK altas).
        The second set provides the surface area for each
        hemisphere without including, for example, the pial
        surface that you see in the hippocampus which is not
        accurate and one should not care about. In the end,
        the second set gives you the sum of the areas in
        aparc, thus, you can just make a sum of that
        parcellation if you want. I just realized that.

        2) No. In the new stats file, the value that you
        want is at the bottom:

        # ColHeaders StructName NumVert SurfArea GrayVol
        ThickAvg ThickStd MeanCurv GausCurv FoldInd CurvInd

        And when running aparcstats2table that's the value
        you should get in the table. I think that # Measure
        Cortex, WhiteSurfArea, White Surface Total Area may
        be including more stuff since it is bigger.


        If what you want is only the total hemisphere
        surface area you only need to run the second set of
        commands. If you want the area of each DK altas
        parcellation then run the first set and then simply
        add them to get total hemisphere surface area.


        Someone from Freesurfer staff will correct me if I'm
        wrong. (Please) I'm Ccing Doug since he was replying
        to your previous emails.

        Let's wait for their feedback.

              Thanks Andreia, this does appear to have
              worked. Please forgive my ignorance but
              I do just want to double check two

The first commands you have given provide the stats for

the two hemispheres of the cerebral cortex only based on the pial surface, whereas the second set of commands provide the pial boundary stats for the whole brain rather than just cortex?

The surface area value that I am looking for (grey

matter surface area at the grey/pial boundary) is listed in the new stats table next to: # Measure Cortex, WhiteSurfArea, White Surface Total Area, ?

  I use FS 5.0.

  Is this what you want?

You can run something like

cd $SUBJECTS_DIR/subject

mris_anatomical_stats -mgz -cortex label/lh.cortex.label -f stats/lh.aparc.pial.stats -b -a label/lh.aparc.annot -c label/aparc.annot.ctab subject lh pial

The "Measure Cortex" fields in the output stats/lh.aparc.pial.stats will be measures of the pial surface as will the SurfArea, MeanCurv, GausCurv, FoldInd, and CurvInd fields for each ROI (thickness and number of vertices will stay the same)

Just to double check I understand you correctly, where the output says "# Measure Cortex, WhiteSurfArea, White Surface Total Area" this is now the surface area of the pial surface even though it is labeled White?

          I think they will be created in the
          current dir.

          I use FS 5.0.

          Is this what you want?


          Best,

                Hi all,
    I messed up this question recently so
    just want to clarify and try again. We
    want to know the cortical gray matter
    surface area of our subjects but are
    unclear about how to get this info.

    ?.aparc.stats reports:

    Measure Cortex, WhiteSurfArea, White
    Surface Total Area, XXXX, mm^2

    How about the gray matter?

    Thanks,
    Will

correct, unfortunately, the "White" label is hard coded into the program.

You can run something like

cd $SUBJECTS_DIR/subject

 mris_anatomical_stats -mgz -cortex label/lh.cortex.label -f
stats/lh.aparc.pial.stats -b -a label/lh.aparc.annot -c
label/aparc.annot.ctab subject lh pial

The "Measure Cortex" fields in the output
stats/lh.aparc.pial.stats will be measures of the pial surface as
will the SurfArea, MeanCurv, GausCurv, FoldInd, and CurvInd fields
for each ROI (thickness and number of vertices will stay the same)

    Sure. We'd like to know how to find the surface area of the
    cortical grey matter from the pial surface. So specifically,
    what is the surface area of the pial/grey matter boundary of
    the cortex for each hemisphere?

    We're using Freesurfer v5.3 on Centos 6.

                        Hi Will,

                        Just to clarify, what version of FS are
    you using? I
                        think it might not be 5.0 and I don't know if
                        everything aplies if we are using different
                        versions.


                        1) Yes, it is only based on the pial
    surface (and
                        these command lines are for the aparc, DK
    altas).
                        The second set provides the surface area
    for each
                        hemisphere without including, for example,
    the pial
                        surface that you see in the hippocampus
    which is not
                        accurate and one should not care about. In
    the end,
                        the second set gives you the sum of the
    areas in
                        aparc, thus, you can just make a sum of that
                        parcellation if you want. I just realized
    that.

                        2) No. In the new stats file, the value
    that you
                        want is at the bottom:

                        # ColHeaders StructName NumVert SurfArea
    GrayVol
                        ThickAvg ThickStd MeanCurv GausCurv
    FoldInd CurvInd

                        And when running aparcstats2table that's
    the value
                        you should get in the table. I think that
    # Measure
                        Cortex, WhiteSurfArea, White Surface Total
    Area may
                        be including more stuff since it is bigger.


                        If what you want is only the total hemisphere
                        surface area you only need to run the
    second set of
                        commands. If you want the area of each DK
    altas
                        parcellation then run the first set and
    then simply
                        add them to get total hemisphere surface area.


                        Someone from Freesurfer staff will correct
    me if I'm
                        wrong. (Please) I'm Ccing Doug since he
    was replying
                        to your previous emails.

                        Let's wait for their feedback.

                              Thanks Andreia, this does appear to have
                              worked. Please forgive my ignorance but
                              I do just want to double check two
                              things;

            1) The first commands you have given provide the stats for
            the two hemispheres of the cerebral cortex only based on
            the pial surface, whereas the second set of commands
            provide the pial boundary stats for the whole brain rather
            than just cortex?

            2) The surface area value that I am looking for (grey
            matter surface area at the grey/pial boundary) is listed
            in the new stats table next to: # Measure Cortex,
            WhiteSurfArea, White Surface Total Area, ?

            Thanks again,
            Will

                  Hi Will,

                  I use the following commands to get
                  surface area from the pial surface:


                  In the subject label dir:


                  mris_anatomical_stats -mgz -cortex
                  ../label/lh.cortex.label -f
                  ../stats/lh.aparc.pial.stats -b -a
                  ../label/lh.aparc.annot -c
                  ../label/aparc.annot.ctab SUBJ lh pial

                  mris_anatomical_stats -mgz -cortex
                  ../label/rh.cortex.label -f
                  ../stats/rh.aparc.pial.stats -b -a
                  ../label/rh.aparc.annot -c
                  ../label/aparc.annot.ctab SUBJ rh pial



                  Then run aparcstats2table using
                  aparc.pial instead of aparc (only
                  because I called this new parcellation
                  aparc.pial)



                  To get the total surface area of each
                  hemisphere I use:

                  In the subject stats dir:


                  mris_anatomical_stats -l
                  ../label/lh.cortex.label -f
                  lh.total_pial.stats -b SUBJ lh pial

                  mris_anatomical_stats -l
                  ../label/rh.cortex.label -f
                  rh.total_pial.stats -b SUBJ rh pial

                  Then run aparcstats2table using
                  total_pial instead of aparc (again, only
                  because I called this new parcellation
                  total_pial. You may call it whatever
                  you'd like)



                  Just remeber to leave the specified dirs
                  when creating the tables. If you dont't
                  I think they will be created in the
                  current dir.

                  I use FS 5.0.

                  Is this what you want?

That is the surface area of the cortical GM where it has its junction with the WM. Or do you want the surface area of the pial surface?
