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
