Dear doug, bruce and others, Previously I could not view " freeview -f $SUBJECTS_DIR/fsaverage/surf/lh.inflated:overlay=lh.gender_age.glmdir/lh-Avg-thickness-age-Cor/mc-z.negative.sig.cluster.mgh:overlay_threshold=2,5:annot=lh.gender_age.glmdir/lh-Avg-thickness-age-Cor/mc-z.negative.sig.ocn.annot " from the "http://surfer.nmr.mgh.harvard.edu/fswiki/FsTutorial/GroupAnalysis". The freeview did represent 3 images. But it reported a something about no geomatric information and I couldnot configure the overlay(When I clicked the "configure overlay", it stopped without any response). My OS is CentOS 6.5 desktop version, and graphic card is NVIDIA GEFORCE GTX 650 and setup the NVIDIA driver. Freesurfer version is freesurfer-Linux-centos6_x86_64-stable-pub-v5.3.0.tar.gz.My computer has 2G memory and 4 processors. I need help to fix it. If anyone have viewed sample data or other data(*.inflated, *sig.cluster.mgh,and *sig.ocn.annot) simultaneously successfully by freeview just as above, would you please tell me some information? The information I need is Freesurer version, Centos version(desktop or others) and something in CentOS setup, graphic card version and its driver, memory size. Thanks very much, doug, brucen and others. Any reply will be highly appreciated. All the best. Rujing Zha

Dear Ruopeng, Thanks for your help, Ruopeng.I learned the groupanalysis by manu ofhttp://surfer.nmr.mgh.harvard.edu/fswiki/FsTutorial/GroupAnalysis. I ran this command on your tutorial data (buckner data). Would you please tell me where my hardware setup is inappropriate? Thanks. All the best. Rujing Zha

Hi Bruce and others, Thanks Bruce. I had installed the centos6.5 x86_64 in my computer, and setup the freesurfer-Linux-centos6_x86_64-stable-pub-v5.3.0.tar.gz, and I setup the nvidia drivers completely. Then I tried to run this command: freeview -f $SUBJECTS_DIR/fsaverage/surf/lh.inflated:overlay=lh.gender_age.glmdir/lh-Avg-thickness-age-Cor/mc-z.negative.sig.cluster.mgh:overlay_threshold=2,5:annot=lh.gender_age.glmdir/lh-Avg-thickness-age-Cor/mc-z.negative.sig.ocn.annot . It did present the underlay(lh.inflated),overlay and annot, but it suspended when I click the button "configure overlay". Then freeview were suspended. The CPU ran "100%",and memory ran "23%". There was nothing to do but terminated it manually in the command console by "ctrl + c". I want to know why I cannot configure overlay. Is it a poor graphic card or CPU or memory? My graphic card is "NVIDIA GeForce 8600 GT", and CPU is "Intel(R) Core(TM)2 Quad CPU Q6600 @ 2.40GHz 2.40GHz", and RAM is 2.00G. Thanks Bruce and others. All the best. 2014-01-03
