Hi there, back again with another newbie question that I cant seem to find an answer to within the SUMA pdf. I have recently begun working with SUMA and was curious about the manner in which to map the volumetric data to the surface. To start I used FreeSurfer to create the surface models for my subjects and @SUMAMAKESPECFS worked perfectly to create my appropriate files. From there I also used @SUMA_AlignToExperiment for my surface and experimental anat files with no problems. The next step in the pdf just states to map your volumetric data to to surface using command line or interactively. That said I tried this and the results were terrible. So taking a step back I reran my data using the anat from @SUMA_Align and removed the align and tlrc. sections. This actually produced data that mapped onto the surface anat pretty much perfectly. However, being new to this I cant help but feel like I am missing a crucial step to make the process even better. I found 3dVol2Surf but haven't fully deciphered the help file from that yet. Just looking for some input on this, thanks in advance 8).
