Hi Jasmin

actually things look pretty reasonble given the degree of motion corruption. Is it still running? I would expect it to finish ok. I doubt you can get realiable thickness estimates off this kind of data, but you should be able to do e.g. fMRI analysis.

There were a bunch of big defects so the topology fixing took a lot longer than usual, but it did complete

cheers

Hi Bruce,
I uploaded two subjects directories to the FTP site. 

Thanks,

      you can put it on our ftp site:

      but at that point you might as well tar and gzip the entire
      subject dir and upload it

            Thanks for the reply, below is a couple of sentences

            mom=0.00, dt=0.05.


            I also attached a screenshot of the log. 


            Is there a place I should upload the files?


            Thanks,

                  Hi Jasmin

                  typically that means there is a big
            topological defect, which
                  definitely can be caused by motion. What is
            the last couple of
                  lines of the recon-all.log file of one of the
            subjects? Can you
                  upload an image we can look at?

                  cheers

                        Hello,
                        I have used FS6.0 to do recon-all on
            about 57
                        brains, but for some reason,
                        recon-all is not working on some brains,
            recon-all
                        is not able to get past
                        "Automatic topology fixer", after the
            command has
                        been running for 24 hours.

                         Is it possible there is too much motion
            in the
                        image? Or does FS6.0
                        possibly take longer to complete for
            some brains?

                        Thanks,
                        Jasmin
