I always use FORTRAN for such tasks, especially if speed is important.

Ho,
A second the vote for OmpF, but many porins could do. Although it is a little
harder to purify from native membranes, OmpF has the advantage that it can be
crystallized in about 1-2 hours from a simple detergent solution with different
PEGs AND (!!!) it is as stable as a rock (you can drop
One thing to keep in mind is that there's usually a trade-off between
setup (writing and testing) and execution time. For one-off data
processing, I'd focus on implementation speed rather than execution
speed (in other words, FORTRAN might not be ideal unless you're already
fluent with it).

A similar remark was made to me by David Blow, while he was on sabbatical at
UNC in the 1980s, working with the UNC Computer Science Department and in a
moment of intense frustration with the overpowering ignorance of fortran and
the enthusiasm for Unix exhibited by that department.

I agree with Pete. Moreover, Python doesn't have built-in statistic
functions but adding package (numpy and scipy in this case) is very simple.

Hi Jacob,
As the preceding discussion has illustrated, there are obviously a
number of options, nearly all of which will work well for what you
describe. As Pete Meyer suggested above, the best language may be the
one you already know (I also echo his suggestion to test your code on

Depends on if you like the object model, some don't. In the end it
really boils down to what you're used to and what you've learned to
use.
Now is the time when I start waxing nostalgic about the "old days" when there
used to be entire threads on this bulletin board about Fortran format statement

Hi everyone,
I am trying to show that a ligand underwent catalysis during a soaking
experiment.
One of the things I would like to show is the geometry of the ligand, bond
angles/lengths, dihedrals, etc...
One of my models has a hi-res of 1.18A and the ligand density is really clear
and complete.
Dear all,
Thanks for your cooperation.
Regards,
Sudipta.

Now it does!
It is the lack of compatibility between different versions mentioned by
Ethan that really put me off learning PYTHON. In contrast, the

modern FORTRAN compiler. The only significant 'new' features that I now
use are dynamic ar

Python is backwards compatible. I have reams of code I wrote in python 2.3 that

Ethan,
I think majority of your complaints about python result from its very
purpose - to be readable/portable for the sake of facilitating rapid
implementation. There are many other languages that provide tools to

You can do unrestrained refinement in refmac, at your resolution it may
be OK. If you want to keep protein restrained, you can either use
harmonic restraints or come up with a special cif-file for your ligand
with large esd targets. There is no direct way to tell refmac to

I'd just use a decent shell scripting language (like zsh) in conjunction with a

In case it helps… After you've done unrestrained refinement, you can use
prosmart to generate external self-restraints to the current conformation
(using the -self_restrain keyword). This is flexible - you can specify residue
ranges, and it works for protein, ligand, DNA/RNA, waters, etc. These
