Ah, the subject was missing Neutral from all three runs. Removing them from the sessid gets rid of the error. Thanks! Keith -- Keith Yoder PhD Student, Integrative Neuroscience Social Cognitive Neuroscience Laboratory The University of Chicago 5846 S. University Avenue, Kelly 312 Chicago, IL 6063

Hi Keith, if you don't have any Neutral in a session, you can't do a Good-Neutral comparison. If you have multiple runs within a session, then it should be ok. doug On 12/07/2012 03:02 PM, Keith Yoder wrote: > Hi Doug, > > I'm having a similar problem. Subjects had the opportunity to > classif

Hi Doug, I'm having a similar problem. Subjects had the opportunity to classify stimuli into one of three categories (Good, Bad, Neutral). For some subjects, one of more of the runs did not contain any stimuli that they classified as Neutral. If I want to look at a contrast that compare Good-Ne

If you have an event type for which there is no event, then that is definitely the problem. Let me know if it is not that. doug Sid Kundu wrote: > It is attached. Finn mentioned it may be due to an event number being > missing from the particular subject, which could be possible in the > analys

It's probably a problem with your design. Can you send me the Xtmp.mat file? doug Sid Kundu wrote: > Hi Doug, > > I created a new first level analysis along with new contrasts and > event numbers for a group of subjects I had previously done analyses > on. All but one of the subjects finished s

Hi Doug, I created a new first level analysis along with new contrasts and event numbers for a group of subjects I had previously done analyses on. All but one of the subjects finished selxavg3 without error, but one subject gave the following error: Saving X matrix to /home/sidkundu/freesurfer/
