Hello,

Interesting. Would you be able to email some log files to me? I can send an address and some details (like adding -save_details DD and possibly -debug DDD).

Just to be sure, are there supposed to be 437 time points or 438? The error suggests that 438 time points of files are on the command line.

Thanks,

Yes, please.

Just to be sure you see it, I replied with a private message.

Thanks for the details.

Indeed, it looks like you have a single extra slice in there for some reason, at the end, starting over at echo 1. Dimon expects all of the data to be valid, so I would suggest renaming or moving it (never delete, just to be safe). Your command specifies starting with "MR", so it would be enough to avoid that.
