Download from structure database at EBI or RCSB

You need to be connected to the Internet. From the File menu select Download coordinate file and in the download window enter the 4-letter code for a model (e.g 1alz). If you click return in the code window then a default name for the local PDB file is shown in the line below. Click the Apply button and the file will be downloaded to your computer and read into CCP4mg.

If you do not know the 4-letter code for the structure that you want then click on the View server web page button to bring up a web browser showing the structure database query page. Once you have found the structure you want you can use either the database download option or the CCP4 interface. If you have difficulty reading a file from a database then check that it is not a PDB file wrapped in an HTML file.
