Hi,
I'm running into an error with selxavg ('Input to SVD must not contain NaN or Inf') that has been posted before on the mailing list but I couldn't find a solution to it.
The command was selxavg-sess -sf sessid -df sessdir -analysis loc-sm3. The output of the log file is: selxavg-sess log file $Id: selxavg-sess,v 1.15 2006/01/06 02:37:22 greve Exp $ uid=502(lreddy) gid=502(lreddy) groups=502(lreddy), 81(appserveradm), 79(appserverusr), 80(admin) /Volumes/donnees/GR/gr_analysis/kan_gr_006 /Applications/freesurfer/fsfast/bin/selxavg-sess -sf sessid -df sessdir -analysis loc-sm3 Darwin g5-leila.local 8.11.1 Darwin Kernel Version 8.11.1: Wed Oct 10 18:23:28 PDT 2007; root:xnu-792.25.20~1/RELEASE_I386 i386 i386 Fri Mar 12 17:07:53 CET 2010 selxavg: Command not found. ------------------------------------------- /Volumes/donnees/GR/gr_data/kan_gr_006 Fri Mar 12 17:07:53 CET 2010 -------------------------------------------------------- /Volumes/donnees/GR/gr_data/kan_gr_006/bold selxavg2 -TR 2.0000 -parname loc.para -o loc-sm3/h -i 018/fmc-sm3 -i 019/fmc-sm3 -i 020/fmc-sm3 -cfg /Volumes/donnees/GR/gr_analysis/kan_gr_006/loc-sm3/analysis.cfg -ipr 1.40625 -pomnibus loc-sm3/omnibus/fsig -fomnibus loc-sm3/omnibus/f -------------------------------------------------------- cat: /Applications/freesurfer/fsfast/docs/version: No such file or directory --- Parsing Config File: /Volumes/donnees/GR/gr_analysis/kan_gr_006/loc-sm3/analysis.cfg ---- -gammafit 2.25 1.25 -timewindow 30 -prestim 6 -polyfit 1 -TER 2 -nskip 0 -fwhm 0 -extreg mcextreg -nextreg 3 -rescale 1000 Logfile is loc-sm3/h_sxa.log matlab file is /tmp/sxa_5739.m ----------- Matlab file -------------- % Matlab file for selxavg2 Fri Mar 12 17:07:53 CET 2010 % This file may be deleted % /tmp/sxa_5739.m global QuitOnError; QuitOnError = 1; r = fast_selxavg( '-TR', '2.0000', '-parname', 'loc.para', '-o', 'loc-sm3/h', '-i', '018/fmc-sm3', '-i', '019/fmc-sm3', '-i', '020/fmc-sm3', '-cfg', '/Volumes/donnees/GR/gr_analysis/kan_gr_006/loc-sm3/analysis.cfg', '-ipr', '1.40625', '-pomnibus', 'loc-sm3/omnibus/fsig', '-fomnibus', 'loc-sm3/omnibus/f'); if(r==0) fmri_touch('/Volumes/donnees/GR/gr_data/kan_gr_006/bold/loc-sm3/selxavg.ok.5739'); end qoe;
