Schedule


RAID information

The structure data on Tirith webserver are located on a four-slice redundant array of hard drives and backed-up to another RAID located in the department server room. This was implemented to introduce fault tolerance to disk crashes. Nevertheless we continue to encourage users to download and back up their data. The most important files are the CIF, RES and HKL. The most recent version of the crystal suite software, SHELX-2015, incorporates the RES and HKL files into the CIF, in which case the CIF alone is sufficient.

Utilities

Mercury is an excellent and free visualization program for Windows and for Mac OSX developed by the good folks that create the Cambridge Structural Database. This is particularly useful for examining extended structures with H-bonding for example.
