Hi I have create my own annot file and lookuptable for cortical parcellation. How I can implement my own parcellation in aparc+aseg.mgz file.

I am also stuck on how to update the FreeSurferColorLUT.txt file?

Please help. Thanks Sarbani

Hi Das

can you check if there is an embedded colormap in your .annot file?You can do this by running mris_info on it.

Yes there is embedded color file in my annot file. Here is the extract of lh.aparc.annot that I created.

ok, then what is the next step in your processing? And where does it go wrong? Does the annot display in the proper colors on the surface?

ok, then what is the next step in your processing? And where does it go wrong? Does the annot display in the proper colors on the surface?

Sorry, I lost track of what was going on in your previous emails Bruce On Fri, 28 Apr 2017, Das S. wrote:

Yes there is embedded color file in my annot file. Here is the extract of lh.aparc.annot that I created.

Hi Das

can you check if there is an embedded colormap in your .annot file?You can do this by running mris_info on it.

Hi I have create my own annot file and lookuptable for cortical parcellation. How I can implement my own parcellation in aparc+aseg.mgz file.

I am also stuck on how to update the FreeSurferColorLUT.txt file?

Please help. Thanks Sarbani
