You will need to run 500 different recon-all jobs. Obviously, if you run
them on a single computer, it will take a long time, so you will need
access to a cluster. Or you can buy time on a cloud service.

I put that in there mainly as a quality check to automatically flag
something that has gone wrong. I think something went wrong if the value
is 0.65 (unless you have very atrophied subjects). You will have to take
a look to see what might have gone wrong.

Dear FS Team,
We are running recon-all for a large dataset and 5 of the cases keep getting stuck at the exact same spot. It is the point at which the following has just been displayed on the screen:
#@# WM Segmentation Wed Aug 30 17:34:40 EDT 2017
mri_segment brain.mgz wm.seg.mgz
doing initial intensity segmentation...
using local statistics to label ambiguous voxels...
computing class statistics for intensity windows...
WM (107.0): 105.5 +- 6.4 [91.0 --> 125.0]
GM (78.0) : 81.0 +- 6.1 [56.0 --> 94.0]
setting bottom of white matter range to 87.1
setting top of gray matter range to 93.2
doing initial intensity segmentation...
using local statistics to label ambiguous voxels...
For these 5 cases it will sit at this step apparently still running for over a week without any change before I cancel the job. There does not seem to be anything special about these 5 cases either in terms of their header information or visually. We have not found any artifacts in the images except for some minor ringing which is present in many images in the dataset, not just these. The rest of the cases of the dataset all ran to completion and produced all of the files we were expecting, but a subset of them seem to have a related issue where most of the wmparc.mgz labelmap is unsegmented white matter. Only the very edges and the very center are getting designated as something other than this label. The rest of the files in the "mri" directory such as aparc+aseg.mgz and so on are equally as affected by this. Do you know what could be going on here? I would be happy to give you any more information that could be helpful.
Best,
Elisabetta and Nate

Hello,
Quick question. If I scanned a single subject across several sessions and
want to do a fixed effects analysis on that subject's brain (without
registering to MNI or Talairach space), how do I go about doing this? I am
trying to us isxconcat-sess and then mri_glmfit, but I am not seeing an
option to simply do the analysis in native space instead of registering to
a standard brain. Is there a way to do this besides taking the end result
of the analysis and doing the reverse registration back to the subject's
brain?

you have to create the directory before you can cd to it. If you don't
know how to create a directory in unix, then you should take some time
to learn unix before trying to run FS.

do you mean the surface area of the inside of the skull? We do not
segment the skull, so no such area measure is possible.

the first question is whether this is multi-echo data? Assuming it is,
you can
mv 001.mgz multiecho.mgz
mri_concat --rms multiecho.mgz --o 001.mgz

You could do it in matlab, something like
waveforms = fast_vol2mat(MRIread('waveform.nii.gz'));
% this will be a matrix ntimepoints by nvertices
You can then load the label with read_label.m and then pull out the
columns from waveforms that you want. Make sure to account for the fact
that the label indices are 0-based but matlab uses 1-based

I've run many hundreds of scans repeatedly and found variance between
versions of FreeSurfer, but identical output within a version. Something
must have changed between runs. Perhaps you could try comparing the log
files and see where the deviations begin.

Is it normal? If it is, why is it so?

Dear Doug,
Sending the FSGD described in our original email as failing due to it being "ill-conditioned or badly scaled" with DOSS [0 1 0 0 0]. It is titled "FAILS_N47_edited_BL_CT_PiB_centAge_fsgd.txt".
The other one is the one that runs and gives expected results with a DOSS contrast [0 1 0 0].
Thanks so much.
Best regards,
Fred

can you send the fsgd file for the analysis that is failing?

Hi everyone,
Is there a freesurfer file/file format for the *average* MNI brain (as
opposed to fsaverage which is just based on different subjects)? Or is
there a way to turn MNI coordinates into freesurfer space? Thanks so much!

Hi,
e.g., by considering two or more groups, I would like to map the clusters
reporting the covariance between the functional connectivity or cortical
thickness (dependent variable) and age, tacking in account the group
differences.
Instead, I'm not interested to map the group differences, taking in account
the nuisance factors.
Thanks,
Stefano

in the one that fails you are including the binary gender as a
continuous variable, which will fail in FSGD. All catagorical variables
need to be coded as classes. see

you would need to create a contrast to look for the interaction. If you
have four gruops and 1 covariate, then it would be
0 0 0 0 1 -1 0 0
0 0 0 0 1 0 -1 0
0 0 0 0 1 0 0 -1

You need to map them into the same space. You can use mris_apply_reg to
map one subject into the other or you can use mris_preproc to put them
both into fsaverage space

Hi Freesurfer Team!. We are trying to use TRACULA to analyze the structural connectivity of PD patients scanned on a 3 tesla Philips Ingenia. We have run the tutorial data without any problems but encounter errors when using our own data. We ran recon-all on all of our subjects without any problem and follow the exact steps that worked for the tutorial data but encounter different errors when using the dcm or nii version of the DTI scans. Our nii files go from scanner to CD to Osirix to DICOM to dcm2nii which gives us the nii files and the bvals and bvecs. Here is the error for the nii DTI scans (included bvals and gradients in the config file for the nii files).
