Hi Maedeh
what does the annotation file LDestrieux200 look like? If you apply it to the subject test1 does it work?
if you want to send us that subject dir and the lh.LDestrieux200.annot and lh.Destrieux200.gcs files we will take a look cheers Bruce
p.s. sorry for missing your email the first time

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 $Id: mris_ca_label.c,v 1.37 2014/02/04 17:46:42 fischl Exp $ $Id: mrisurf.c,v 1.781.2.6 2016/12/27 16:47:14 zkaufman Exp $ reading atlas from lh.Destrieux200.gcs... average std = 0.2 using min determinant for regularization = 0.000 0 singular and 570 ill-conditioned covariance matrices regularized input 0: MEAN CURVATURE, flags 0, avgs 5, name mean_curvature labeling surface... relabeling using gibbs priors... 000: 479 changed, 114679 examined... 001: 18 changed, 2844 examined... 002: 1 changed, 89 examined... 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 /home/user/Desktop/Maedeh/test1/label/lh.myDestrieux200.annot... classification took 0 minutes and 3 seconds.
I would be grateful if u could help me. Cheers, Maedeh,
