I'd just use a decent shell scripting language (like zsh) in conjunction with a unix tool like awk. But the gnuplot option sounds ideal. Bill William G. Scott Professor Department of Chemistry and Biochemistry and The Center for the Molecular Biology of RNA 228 Sinsheimer Laboratories

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

It is possible to force Pointless to select a particular solution, using the Find or match Laue group option in CCP4i. The default option here is Determine Laue group but if you select the Choose a previous solution checkbox you can specify the solution you want Pointless to select, by

Hi Yuri, If you have access to mogul you can get an understanding of what your geometry should be based on the small molecule database. Of course not everything is well represented so if your ligand is unusual this will flag up in lower statistical significance. Mogul will allow you to

Like most computer users and many scientists I don't write scripts to organize or analyse my data unless I get desperate. I've used both Python and Perl a few years ago, but it would take quite a lot of time and effort and staring at on-line tutorials to get back into either of them right now.

In my opinion, the Python equivalent of your pseudo-code is fairly close to how you would write the instructions logically. But then maybe not everyone thinks in the same way that I do :-) for x in range(1, 10): if age_of_person(x) 50: print name_of_person(x), is an old man (or woman) Of

It turns out that the syntax and semantics of all reasonable programming languages are very similar, or fall into only a few classes (e.g. C-like, S-expressions, etc.), so once you are fluent in one from a class, it's easy to pick up the others. This can't be said of natural languages, which
