[PyMOL] about Display CCP4 Maps

[lina <lin...@gm...>]

Hi,

I went through the pymolwiki and cross this page:

http://www.pymolwiki.org/index.php/Display_CCP4_Maps

I have some questions:

1] do I need generate the map from ccp4

 (I have already installed the ccp4i, but seems not easy to know how
to get the map)

2] For small molecular (ligand), the ccp4 is the best way to obtain
its  electron density map?

Seems those questions are not so-pymol-related, but I wish if someone
are familiar with this, can give me some advice??

Those questions might be easy, but to me at present it seems very confusing.

Thanks with best regards,
