Hi Das
when you give mri_ca_label the option:
-l 100307/label/lh.cortex.label
you are telling it to mask out what it thinks are non-cortical areas and assign them unknown. Is this a problem?

Hi, I have created an .annot file from label files using mris_label2annot command.
mris_label2annot --s 100307 --h lh --no-unknown --ctab 100307/label/eq_parcellation_ label/MyColorLUTnew.txt --a eqnew40aparc --ldir 100307/label/eq_parcellation_label/
Then I have created a .gcs file from the above .annot file.
mris_ca_train -t 100307/label/eq_parcellation_label/MyColorLUT.txt lh 100307/surf/lh.sphere.reg 100307/label/lh.left40aparc.annot 100307 100307/label/lh.reg40aparc.gcs
Then from the .gcs file I have another .annot file.
mris_ca_label -l 100307/label/lh.cortex.label -aseg 100307/mri/aseg.presurf.mgz 100307 lh 100307/surf/lh.sphere.reg 100307/label/lh.eqnew40aparc.gcs 100307/label/lh.aparc.annot
The 2nd annot file is corrupted and showing a big gray patch.While checking the annotation file in matlab, found that the those vertex on the .annot file were not assigned any colorcode from colortable. Here is the content of MyColorLUTnew.txt:

Any help will be much appreciated, why the file is getting corrupted in the 2nd step?
Thanks Sarbani
