Hi Everyone,
I am trying to extract volume and thickness data from a list of subjects for several ROIs that Freesurfer does not automatically define (ie. Broca's area). My plan was to load a .dat table into Qdec with a column of subject IDs and a column with a dummy continuous variable. Then I would use Qdec to draw some labels, which I would later use with mris_anatomical_stats.
So far, I used Qdec to draw a label and am now trying to map the label to all the subjects. However Qdec keeps giving me errors. (I'm using Freesurfer v4.0.2).
(1) The first error continuously pops up, but I seem to be able to ignore it:
ERROR: In /usr/pubsw/packages/KWWidgets/CVS/src/KWWidgets/vtkKWTkUtilities.cxx, line 221 vtkKWQdecApp (0xdf9640): Script: FsgdfPlot_IsWindowShowing 0 Returned Error on line 1: invalid command name "FsgdfPlot_IsWindowShowing" Stack trace: invalid command name "FsgdfPlot_IsWindowShowing" while executing "FsgdfPlot_IsWindowShowing 0"
I saw that a previous user also had this problem and was told that it was due to Freesurfer v4.0.2 missing the fsgdfPlot.tcl file. However, I checked my $FREESURFER_HOME/lib/tcl directory, and it appears to already have this file, so I'm not sure if this is the problem.
(2) The other error I get, which seems to be causing the mri_label2label command to fail is this:
ERROR: there is a vertex in the label that cannot be matched to the surface. This usually occurs when the label and surface are from different subjects or hemispheres or the surface has been changed since the label was created. Label point 33: vno = 175287, max = 163842 command failed: mri_label2label --srclabel /ifs/edevel/UCLA_FREESURFER/OUTPUT/qdec/Jessie/ROI_labels/lh.insula_dummydat_11-18-10.label --srcsubject fsaverage --trgsubject 20171 --trglabel /ifs/edevel/UCLA_FREESURFER/OUTPUT/qdec/Jessie/ROI_labels/lh.insula_dummydat_11-18-10.label --regmethod surface --hemi lh
This seems to be the more pressing problem, and I'm lost as to how to fix it.
Any suggestions would be greatly appreciated. Thanks in advance!
