Hi all,
I was trying to get maps using the *fetch PDB and Map using EDS
option* in coot, however the map would not open I am using coot
version 0.6.2 was wondering if anybody else had similar problems and
how to fix this, the following is the error message I get. It used to
work fine with a previous version of coot.
If you have 0.7-pre
Extensions -> Get from PDBe (I like to keep my refmac pretty up to date).

It appears that the Electron Density Server could not calculate a map

The EDS doesn't speak to me at all. Maybe I am asking in the wrong
places...
These cryptic messages are what you get from Coot when there
is no map on the server.
... no mtz file on the server (which probably amounts to the same thing).
I can see from the RCSB web page that there is
no EDS link in the "Experimental Details" section, which also happens
when the EDS comes up empty.
When the EDS fails to calculate a reasonable map for an entry they do
not tell us why.
Coot downloads the web page too and parses it for message referring to
the non-existence of a reliable map. It lets you know if it finds such a
thing.
If they knew what the problem was they would fix it
themselves. They remain silent hoping that the authors of the entry
will contact them and give them some help. It is absolutely amazing that
they can calculate as many maps as they do.
wwPDBs are better at making parsable/convertible data these days (in my
experience).
