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

Hi Laleh,
If your preferences (Favorites… Preferences, category: Fetch) are set to save files in a download directory, they are already automatically saved locally in a subdirectory named EDS in the download directory.  However, these files are in the .omap  format, not MRC.

Since you can fetch from EDS with the "open" command and write out a map in MRC format with the "volume" command, one possibility is to make a Chimera command script.  Example commands:

open edsID:2fw0
volume #0 save ~meng/Desktop/2fw0.mrc


For combining commands with looping (for example, to process a large set of EDS IDs), see here:

I hope this helps,

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.
