Hi Matteo,

I'm sorry about the problem!

I afraid there are only solution two solutions: 1) use a computer with more memory: the error below tells the program needed more memory than your computer has, or 2) wait for a one of upcoming nightly builds.

Since the release I've already made a number of changes that should help free some memory: for example, I switched from 1/4. to 1/3 gridding, which should significantly reduce the memory consumption (and speed up the calculations too).

Hi Pavel,
I downloaded the last released version of phenix (phenix-1.9-1692) and I would like to run the "feature enhanced map" command.

However, when I run it I got the following Memory Error that I didn't have in the previous version of phenix.

Thanks in advance
