Hi Dr. Greeve,

I'm certainly making progress with your suggestions but I still seem to be missing information. Overall, the volume I create is either not aligned with the brain itself (namely, the volume for V1 is around the neck if I pass an anatomical scan into mri_label2vol) or the volume I create is in the wrong file type and isn't being recognized as a mgz file (when I pass in functional data into mri_label2vol, the volume is in the right spot in the brain this time and I assume the resulting volume is also functional in nii.gz format; but, like you mentioned, fcseed-config requires an mgh/mgz file which is not my nifti file. It seems to have loaded but I'm still getting an error that fcseed-sess is reading 0 segmentations). To elaborate:

Pass 1:

In an effort to make the binary volume in anatomical space you described, I passed an anatomical scan (orig.mgz) and a registration to the functional data (register.dof6.dat~) into the command mri_label2vol:

mri_label2vol \ --label $SUBJECTS_DIR/B201_mprage/label/lh.V1_exvivo.label \ --temp /Users/caramazzalab/Desktop/Jess/Subjects/B201_mprage/mri/orig.mgz \ --reg /Users/caramazzalab/Desktop/Jess/V1_REST_STUDY/dicomdir/B101/bold/register.dof6.dat~ \ --fillthresh .3 \ --proj frac 0 1 .1 \ --subject B201_mprage --hemi lh\ --o lh.V1_exvivo.mgz

However, the outputted volume was not in the right location in the brain. Instead, the volume was overlaid around the neck instead of truly at V1.

^notice how the volume (where the red cross is) is not in the brain

Pass 2:

In an effort to align the volume with the brain, I reran the mri_label2vol command using functional data and a functional volume output (according to file extension and documentation of what the argument --temp dictates):

mri_label2vol \ --label $SUBJECTS_DIR/B201_mprage/label/lh.V1_exvivo.label \ --temp /Users/caramazzalab/Desktop/Jess/V1_REST_STUDY/dicomdir/B101/bold/001/f.nii.gz \ --reg /Users/caramazzalab/Desktop/Jess/V1_REST_STUDY/dicomdir/B101/bold/register.dof6.dat~ \ --fillthresh .3 \ --proj frac 0 1 .1 \ --subject B201_mprage --hemi lh\ --o lh.V1_exvivo.nii.gz

This functional data argument yielded an ROI in the right place (seen in this figure).

^notice how passing in the functional data created a nice overlay of V1 in the brain on orig.mgz

But this functional volume in format .nii.gz wouldn't do for the next steps of inputs for fcseed-config to be run in fcseed-sess command Namely, as you may know, the fcseed-config and fcseed-sess command looks for .mgz files for segmentations. Notice this error below when trying to use the .nii.gz volume:

------

[ERROR: loading aseg /Users/caramazzalab/Desktop/Jess/Subjects/B201_mprage/mri/lh.V1.mgz]

------

Pass 3:

So I passed in the functional data to align the volume and I changed the output command to a file extension .mgz:

But again, smoke but no cigar. Same error through running the fcseed-sess command:

------

Found 1 segmentations

Computing statistics for each segmentation

Reporting on 0 segmentations

Using PrintSegStat

Computing spatial average of each frame

ERROR: no voxels found in segmentation

------

It seems like pass 1 of mri_label2vol (passing in and outputting anatomical data) is most consistent with your email but the volume produced is not aligned with the subject brain. Would you have insight into why the anatomical mgz file is not aligned with the orig mgz file?

Thank you again Dr. Greeve,

Jess

Those labels should exist in your individual subject's label folder.
There should be a V1 label in there too. You can use mri_label2vol to
create a binary volume in the anatomical space (this will be a volume
where voxels values are either 1 (in V1) or 0 (out of V1)). This volume
will be 256^3, 1mm3, and should go into the subject/mri folder (eg,
lh.V1.mgz). When you run fcseed-config, specify -seg lh.V1.mgz -segid 1
