brix2fsfour reads BRIX maps and writes them out into the XtalView FSFOUR-style.

It is important to know that the FSFOUR format maps (and XtalView) assume that there is an entire unit cell written to the file. In the current version, the map that is written out is expanded to the entire unit cell, but the density is not copied in a crystallographic way to cover the whole cell.

When reading in (any) FSFOUR maps into XtalView, right-click on the Load/write Map button under the Files... dialog and choose "Load Fsfour Format Map (*.map)". Simply choosing the default (reading the file as if it were a text phase file) won't work.

As always, I've only extensively tested this program against many of the things that I do regularly so there are potentially a number of bugs that are creeping about. I've written the program to be very robust so that it should survive even fairly pathological cases, but I've only checked a finite number of these. If you run into any problems, feel free to e-mail me and depending on the problem (and my schedule) I might crack open the code and fix them.

Praise and requests for options that would be useful are also welcome.
