It looks like the ces input is from a surface-based analysis. If you're
label is already on the surface, then no need to do the label2vol step.
If it is in the volume, then you'll need to transfer it to the surface
with mri_label2label with the --paint option

Hello freesurfer experts,
I am trying to extract an average percent signal change from a
functional roi label I created in tkmedit using fsaverage. I followed
previously discussed methods:
1) mri_label2vol --label <name of label> --temp
fsaverage/mri.2mm/orig.mgz --regheader fsaverage/mri/orig.mgz --o
<name of label mask>
2) I checked (tkmedit fsaverage orig.mgz -overlay <label mask>
-fminmax .5 1) and the label looked fine
3) I ran mri_segstats --i ces.nii.gz --seg <label mask from above>
--id 1 --avgwf ces.label.dat
ces.nii.gz is the file from my group analysis (isxconcat-sess) using
the correct contrast
It returns with this error:
ERROR: dimension mismatch between input volume and seg
input 163842 1 1
seg 76 76 93
Is there something I am doing wrong here?
Also of note I tried using the following commands:
1) funcroi-config -label <label mask created from above mri_label2vol>
-analysis <analysis directory> -roi <name of roicfg file>
2) funcroi-sess -sf sessid - roi <roicfg file from above>
But this returns with this error:
ERROR: cannot find
/Volumes/VA_Imaging/Projects/dmiller/COGCON/FSFAST/CC_001_recon/label/label_lh_ACC_correct_mask.mgz
Any suggestions would be extremely helpful.
Thanks,
Danielle
