save manipulated electron density maps in spider

Dear Chimera Developers, I quite often have to manipulate electron density maps in the spider format. When using chimeras volume eraser function, it doesn't allow me to save the new map back to spider or another easy-to-convert file format (such as brix or ccp4). I would be great if you could add such a feature in the next version of the software. Best regards, Jan-Christian Schuette

Dear Jan-Christian, You can save BRIX format from recent versions of Chimera, with "File... Save map as" in the Volume Viewer menu or with the "volume" command. http://www.cgl.ucsf.edu/chimera/docs/ContributedSoftware/volumeviewer/ volumeviewer.html#organization http://www.cgl.ucsf.edu/chimera/docs/UsersGuide/midas/volume.html Probably you just need to get a newer version! This ability was added after the Nov 2007 release. Try getting the snapshot from this month: http://www.cgl.ucsf.edu/chimera/download.html#snapshots Best, Elaine ----- Elaine C.

Hi Jan-Christian, Chimera saves maps in MRC format which is almost identical to CCP4. Programs expecting CCP4 will usually read MRC maps fine as if they were CCP4. As Elaine mentioned, current versions of Chimera can write BRIX format maps. Tom
