Hello FreeSurfer Developers,   This is Erik Jahner, I’m attempting to complete the final step in the tutorial concerning FSFast Functional connectivity walkthrough (http://surfer.nmr.mgh.harvard.edu/fswiki/FsFastFunctionalConnectivityWalkthr...), but for I get the following error when I run the following command: selxavg3-sess -s subj439rest -a fc.lpccseed.surf.lh

I have tried to reinstall MATLAB; I have tried following the instructions to install the runtime environment; I have tried redoing all analysis from scratch. I have noticed that STEP 5 does not work unless I change the -cfg from “L_Posteriorcingulate.config” to “mean.L_Posteriorcingulate.config”. I don’t think this is the problem, but I thought I would point it out.  My session directory is “subj439rest” Instead of titling the sub directory “bold”, I titled it “rest”   1) FreeSurfer version: freesurfer-Darwin-lion-stable-pub-v5.3.0 2) Platform: OSX Yousemite 3) uname -a: Darwin ERIKs-iMac.local 15.5.0 Darwin Kernel Version 15.5.0: Tue Apr 19 18:36:36 PDT 2016; root:xnu-3248.50.21~8/RELEASE_X86_64 x86_64 4) selxavg3-sess-rest-fc.lpccseed.surf.lh-160704110140.log: see attached ___________________________________________________ Here are the command lines I put in for steps 4-8, incase this is of some use: STEP 4 fcseed-config -segid 1010 -fcname L_Posteriorcingulate.dat -fsd rest -mean -cfg mean.L_Posteriorcingulate.config STEP 5 fcseed-sess  -s subj439rest -cfg mean.L_Posteriorcingulate.config STEP 6 fcseed-config -wm -fcname wm.dat -fsd rest -pca -cfg wm.config  fcseed-sess -s subj439rest -cfg wm.config fcseed-config -vcsf -fcname vcsf.dat -fsd rest -pca -cfg vcsf.config  fcseed-sess -s subj439rest -cfg vcsf.config STEP7 mkanalysis-sess -analysis fc.lpccseed.surf.lh -surface fsaverage lh -fwhm 5 -notask -taskreg L_Posteriorcingulate.dat 1 -nuisreg vcsf.dat 5 -nuisreg wm.dat 5  -mcextreg -polyfit 5 -nskip 4 -fsd rest -TR 2 -per-run STEP 8 selxavg3-sess -s subj439rest -a fc.lpccseed.surf.lh
