That subject only has 5 conditions (#6 is not represented in the par file). The easiest thing to do is to randomly assign one of the other conditions to #6. doug Maximilien Chaumon wrote: > Hi Freesurfers, > > I'm trying to selxavg3 my data. > > My design includes 6 conditions including a 0 re

Sharif, what Pedro Paulo suggests is how we use our cluster here at the NMR Center: we simply treat each node as a separate machine, running an instance of recon-all. so with 200 nodes, 200 subjects can be processed. recon-all does not yet support multi-threading, so multi-core machines are not

Depends on your cluster configuration. But if you are using a PBS cluster you can just spawn one recon-all per subject and the queue will take care of them. --- Pedro Paulo de M. Oliveira Junior Diretor de Operações Netfilter & SpeedComm Telec

We don't have anything that will read xls format into a surface. From matlab you can save it as a curv or mgh file as I describe below. I think you can run these under windows since they are simply matlab files. You'd need to have access to them on your windows machine, but you can do this by copyi

Re: [Freesurfer] SUBJECTS_DIR problem when trying to goregister functional and structural data

When you set up the directory, you should have created a filed called "subjectname" in the CA directory. This should be a simple ascii text file with the name of the FreeSurfer subject (as found in $SUBJECTS_DIR). Is that file there and does it have the right name in it? doug Natalia Zaretskay

2009-10-13 Thread Nick Schmansky
is rawavg.mgz the image on the left? if not, and you want the image on the left to be the skull-stripped image, then use that instead of rawavg.mgz. you can use tkregister2 to create a transform aligning your image to a colin27 image, then use mri_vol2vol to reslice the image. nick On Tue, 200
