[Chimera-users] fetching EDS files from the web (python script)

[Tom Goddard]

A few more details.  In Chimera 1.7 and newer fetched files are placed in directories

	Downloads/Chimera/EDS
	Downloads/Chimera/PDB
	Downloads/Chimera/EMDB
	…

i.e. in your computer account Downloads directory there is a directory called Chimera and under that a directory for each database that Chimera has fetched files from.  Also you can fetch many files at once with the Chimera Fetch by Id dialog (File / Fetch by Id) by just entering the database identifiers as a comma separated list, e.g. 1a0m,1a2p,3gfx

As Elaine says the EDS fetch downloads brix format (".omap") so you would need a script to convert those files to MRC format.

>> I'm wondering how I can fetch a bunch of EDS files (from the EDS server) and save them in my local machine in .mrc format. I don't want to do this manually one by one from the user interface... I tried to use open_volume_file with different settings; but it is not working... I'm surprised because this is very starightforward with pdb files. I appreciate your help.
