Check in the rtopy.par file for the polar and make sure it actually says polar (and not eccen) inside On 11/10/2014 01:23 PM, Francesca Strappini wrote: > Hi Doug, thanks for the answer. I have both, 2 runs of polar angle and > 2 of eccentricity. > > Francesca > > On Monday, November 10, 2014,

Hi Doug, thanks for the answer. I have both, 2 runs of polar angle and 2 of eccentricity. Francesca On Monday, November 10, 2014, Douglas N Greve wrote: > > There are a bunch of columns in the design matrix that are 0, meaning > that it expects some kind of stimulus to be there but it was not i

There are a bunch of columns in the design matrix that are 0, meaning that it expects some kind of stimulus to be there but it was not in the parfile. Do you only have eccen for this or do you also have polar? doug On 11/08/2014 11:25 AM, Francesca Strappini wrote: > Hi, I attached the file, t

[Freesurfer] error with fast_selxavg3

Dear all, I'm trying to run a retinotopy analysis in several subjects but it crashed with an error in one subject. I ran this command line: selxavg3-sess -a rtopy.HS.rh -s SUBJ09 and this is the last part of the output with the error message. Any help would be much appreciated. Best Francesca

Hi Leila, yes, the problem is probably in that fsfast sets the TER=.05. I never expected the TR or the event duration to be less than this (silly me). The -refeventdur does not really effect much, it just controls some scaling. Setting it to 16ms is fine. doug On 07/23/2013 08:23 AM, Leila Red

Hi Doug, Thanks for your reply. Yes, it does work with a longer -refeventdur. In fact, I had tried that yesterday before posting my original message but I'd forgotten to make the corresponding changes to the 3rd column of the paradigm file and so kept getting the error message. The shortest I

Hi Leila, does it work if you change the -refeventdur to something larger (eg, 2)? doug On 07/22/2013 06:11 AM, Leila Reddy wrote: > Hi, > > I am running into an error with fast_selxavg3 (NaN values in XtX). Other have > people reported similar problems on the mailing list and I've tried > impl

Hi, I am running into an error with fast_selxavg3 (NaN values in XtX). Other have people reported similar problems on the mailing list and I've tried implementing some of the suggestions (namely, using -nowhiten and checking that all events exist in my paradigm file), but I can't get rid of the
