I'd like to retrieve information wrt XYZ coordinates of vertices within aparc labels.
I have tried the following command: [<subjid>] $ mri_annotation2label --subject EC --hemi lh --outdir ./test_labels --table ../../surface_labels.txt --annotation aparc.a2005s
A total of 57 labels are returned (expecting 94 after looking at the surface_labels.txt file?)
Reading a single label file [test_labels] $ more lh.S_temporalis_transveralis.label
Returns the following structure #!ascii label , from subject EC 394 64599 -35.192 -31.784 11.805 0.000000 64600 -35.842 -31.799 11.554 0.000000 ....etc
1) What is the name & location of the table file I should be specifying to return all 94 labels? Or do I need to include additional flags in my command line? 2) How are the columns ordered within each output file generated by the mri_annotation2label command?
I'm running FSv3.0.5 on linux (Centos 4). The table specified in the wiki help pages (Simple_surface_labels.txt) does not appear to be located in my $FREESURFER_HOME directory...instead, the file <surface_labels.txt> appears in my $FREESURFER_HOME dir.
Many Thanks, Jenifer
