Hi, Chris-
Indeed, I suspect coordinates in a galaxy far, far away might be to blame... Esp. if recentering them fixed the issue.
However, it strikes me as a *bit* odd that that failure didn't happen earlier in the script, then. (Though, it might have been going awry from the initial step, and only reached a breaking point then.) I will email you about getting the original dset, if that is OK.
thanks,
pt
