Thank you. It worked. I have been running a few brains and they have been preprocessed successfully. One brain gave me an error message. Can you please help me address this:

Hi Alan - The file doesn't need to have an extension, .txt or other. But you do need to set bvecfile to the full name of the file, including the extension, if it has one.

Hi Anastasia:

Yes this file does exist but it did not have the *.txt suffix. Maybe I will
change the suffix and run this again.

thanks,

Alan

Does this file exist?
