Dear SIr, I made some analysis based on FS v.2.0. Does the Deprecated version means that the results generated by FSv.2 can't be published???

Hi everyone, Since they don't appear in the documentation accessible through the --help flag, I was just wondering how the flags -n, -thresh, and -distances affect the call to mris_curvature in the inflate2 step of the -autorecon2 stage of recon-all: mris_curvature -thresh .999 -n -a 5 -w -distances 10 10 ?h.inflated (as described on the webpage http://surfer.nmr.mgh.harvard.edu/fswiki/ReconAllDevTable) Thanks in advance for you help, David Romano

Avoid interaction term in qdec?
by Yang, Daniel 06 Sep '13

06 Sep '13

Dear FS Experts, My model has two categorical variable: Diagnosis and Sex. I am interested in the effect of Diagnosis but I want to control the Sex effect. Toward this goal, I want to model two main effects and want to avoid modeling their interaction term. Is this something feasible in FreeSurfer group analysis? Would using DOSS help with the solution? Thanks! Daniel

tool to compare surface files (along the lines of diff)?
by David Romano 06 Sep '13

06 Sep '13

Hi everyone, I'm trying to figure out whether two surfaces which appear identical in freeview are indeed identical. Using diff shows the files are not, but since they're binary, I can't tell whether this difference is simply due to header information that might be embedded in the files, or whether the surfaces do indeed differ. Is there a FreeSurfer command that can be used to determine this? Thanks in advance for your help, David Romano
