HYDROPRO and HYDRONMR

Dear colleague,

I am writing to a group of people interested in the HYDRO computer
programs,  that we develop here at the University of Murcia, to let you
know about two new pieces of software.

I am pleased to announce the availability of a new version (3.c) of
HYDROPRO. Along with some minor corrections, it includes a few new
features. Thus, when the program is used to process a PDB file of a
protein, that contains SEQRES information, the partial specific volume and
the molecular weight are calculated from the PDB data. Also, the
extrapolation to the shell model limit can be (optionally) estimated. 

The other is a new program, HYDRONMR [Journal of Magnetic Resonance 147,
138-146 (2000)], which is intended for the calculation of NMR relaxation of
globular proteins. After the publication of that article, I sent the
program for testing to several specialists. I have not received any report
of serious bugs; just some suggestions for minor corrections, and various
proposals for further work: extensions, enhancements, etc. The minor
corrections have been made in a new version (2.7) of the program, which is
now in our Internet server (see bottom signature), in three versions for
UnixSGI, UnixDEC and MS DOS/Windows. 

I acknowledge that the changes in HYDROPRO are modest, and the
implementation of NMR relaxation is still elementary. However, I am working
actively (although perhaps not as fast as I would like) to include in both
programs improvements and new features. I expect to release a new versions
(perhaps, merging the two programs into a single one) within a few months.
If you wish to keep informed on our developments, please watch regularly
our web site. If you are going to employ HYDROPRO or HYDRONMR, I would like
to receive eventually your feedback.

Best wishes,
Jose.
