External Email - Use Caution
Dear Freesurfer experts,
I am using "mris_divide_parcellation" in order to increase the region
numbers of Freesurfer parcellation output using "recon-all". e.g i have a
200-region parcellation.Now i wanna use "mris_ca_train" and this .annot file
as an input to create an atlas file(.gcs). The code i run and the results on
the terminal are :
$ mris_ca_train lh sphere.reg LDestrieux200 test1
$SUBJECTS_DIR/test1/label/lh.Destrieux200.gcs
computing means for 1 subject
processing subject test1, 1 of 1...
reading colortable from annotation file...
colortable with 261 entries read (originally none)
4210 classifier means computed, 1.6/vertex, 0.5 priors/vertex
computing covariances for 1 subject
processing subject test1, 1 of 1...
reading colortable from annotation file...
colortable with 261 entries read (originally none)
75009 holes filled in class prior array
0 holes filled in gcsan array
writing classifier array to
/home/user/Desktop/Maedeh/test1/label/lh.Destrieux200.gcs...
classifier array training took 0 minutes and 4 seconds.
the problem is that when i use "lh.Destrieux200.gcs" and "mris_ca_label" to
create an annotation file, the result i have is kinda awful !! and when i
check it by tksurfer , the parcellation is not complete and i just see few
regions...i dunno where i am making a mistake.
the code and the results on terminal are :
mris_ca_label test1 lh sphere.reg lh.Destrieux200.gcs
$SUBJECTS_DIR/test1/label/lh.myDestrieux200.annot

reading atlas from lh.Destrieux200.gcs...

003: 0 changed, 5 examined...
000: 241 total segments, 38 labels (248 vertices) changed
001: 203 total segments, 0 labels (0 vertices) changed
10 filter iterations complete (10 requested, 7 changed)
writing output to

classification took 0 minutes and 3 seconds.
I would be grateful if u could help me.
Cheers,
Maedeh,
