After the recent posts on how to use Situs with programs such as EMAN2 /
SPARX that use CCP4 or MRC file formats, I'm happy to announce that Situs
now reads CCP4 or MRC map formats directly. This eliminates the file
conversion step in CCP4- or MRC-based work flows.
There are subtle differences between various CCP4/MRC formats which are
handled gracefully. A detailed documentation can be found here:
http://situs.biomachina.org/fmap.pdf
The classic Situs map format continues to be supported because it still
offers some benefits as noted in the documentation. The format selection is
completely transparent (automatic recognition on input, based on the file
extension on output, i.e. Situs for .sit or .situs, CCP4/MRC otherwise).
Additional map formats such as SPIDER can be converted using the Situs
map2map tool, as before.
If you have a moment take a look also at other recently added Situs features
at http://situs.biomachina.org. Questions or comments are welcome!
Cheers,
