Dear Douglas, The file is created on a mac using the open -e command. I’ve tried running your command:
cat whiplash.fsgd | sed 's/\r/\n/g' > new.whiplash.fsgd However, this makes the file unreadable for FreeSurfer. Any ideas? Thank you in advance, Robby Date: Thu, 21 Aug 2014 13:30:19 -0400 From: Douglas N Greve <gr...@nmr.mgh.harvard.edu> Subject: Re: [Freesurfer] GLM: Error Matric-Scale To: freesurfer@nmr.mgh.harvard.edu Message-ID: <53f62cab.1060...@nmr.mgh.harvard.edu> Content-Type: text/plain; charset=ISO-8859-1; format=flowed It looks like your fsgd file may have been created on a windows computer. Is that possible? Try reformatting it in linux or mac. doug On 08/20/2014 12:58 PM, Robby De Pauw wrote: > > > > > > > > Hi there FreeSurfer > > When trying the GLM-analysis I keep getting the following error.
