nothing yet. Though would you be allowed to install Cygwin on the lab

MAPMAN is an uppsala utility(?) - try hassling the uppsala group :)

You are welcome to use the CCP4 programs which are available online. I
don't think SwissPDB viewer uses CCP4 libs that can cope with the byte/
cross platform problems. I could get a task online that would change the
NT map file into a unix map file. (by running maptona4 twice on the server
which is Linux should do the job?). That would at least let you use Swiss
