use --slabel, not --seg doug

Sure -- should be all here now!

The last email contained the following text: "Hi Doug,

...

Thanks for the response. I used the mri_label2label command: mri_label2label --srclabel <labelfile> --s fsaverage --regmethod vol --paint dmax --trglabel <output> --hemi lh

When I input the output from this into mri_segstats as the --seg volume, I get the error: mri_read(): couldn't determine type of file fsaverage/label/lh_ACC_label_test.label ERROR loading fsaverage/label/lh_ACC_label_test.label

Is there another step I am missing?"

Hi Danielle, can you resubmit this email with the previous correspondence?

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 doug

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
