Hello, I've been running DARTEL for the past two days and came into lab today to discover an error message. I've attached the error message to this email. I checked the SPM Listserv archives and some speculated the error might be due to a memory issue. I'm running DARTEL on an Intel Mac (2.66 GHz on OS 10.6.8) with 4 GBs of ram, so I kind of doubt insufficient memory would cause this issue. Has anyone run into this issue before and found a solution? Thank you, Ian Carroll
