cortical surface parameterization : no gyral parcels
Posted: Fri Sep 07, 2012 1:13 pm
Hi,
We've been trying the Cortical Surface Parameterization pipeline on one left hemisphere with no success. Both texture files "<subject>_L_gyri.tex" and "<subject>_L_gyri_regul.tex" displayed only one or two sulci (in the insula). As inputs, we used the "default_session_manual" sulcal graph parameters; as for parameters, we used "name" as sulcus_identification, "nomenclature/surfaceanalysis/constraint_correspondance.txt" as the file_correspondant_constraint, and
"nomenclature/translation/gyri.trl" as the translation parameter. Are there other parameters to tweak in order to make it work?
Then, we tried the 2012 release of the same pipeline with no success either. In this case, we did not find any gyral parcellisation output. Is it an improved pipeline compared to the previous one? Specifically, what is the name of the gyral parcellisation file?
Cheers,
Francois
