-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 Dear Eike, did you try surface/volume without any extra options? That should work with a few lines of code, e.g. surface xyzin1 yourfile.pdb xyzout yourfile.surface << eof1 RUN STOP eof1 volume xyzin yourfile.surface << eof2 | tee volume.log RUN eof

2012-05-24 Thread Eike Schulz
Hello everyone, I am working on protein RNA complex and would like to verify the oligomeric state from the crystal structure by analytical ultracentrifugation (AUC). To fit data from AUC we need a good estimate of the partial specific volume of the complex, therefore I wanted to retrieve this valu
