[3dem] EMDB accession code format

[Frederic Bonnet]

Hi,

an alpha-numerical tagging method will give EMD-26^(m)x10^(n)
possibilities, where m being the number of letters and n numbers.

take m= 2 n=4 for example it gives 6,760,000 possibilities!

Now if one differentiate between virus, bacterium, filament etc.. then each
categories become a lot smaller.

ie
bacterium: EMD-B-26^(m)x10^(n)
virus        : EMD-V-26^(m)x10^(n)
other        : EMD-O-26^(m)x10^(n)
etc..

It is then also possible to identify the sort of molecule almost
immediately.

Best to keep the number of digits and letters fixed of length and maybe pad
with 0 as you as suggesting if neccessary
so that we do not have to modify the codes too much.

Best.
Frederic.
