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/FsFastFunctionalConnectivityWalkthrough ), but for I get the following error when I run the following command:

selxavg3-sess -s subj439rest -a fc.lpccseed.surf.lh

ERROR: fast_selxavg3() failed\n

I've searched the list and no similar errors have been reported. 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”

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

STEP 8

selxavg3-sess -s subj439rest -a fc.lpccseed.surf.lh
