Thanks to everyone who answered. There are many ways to display the images. Summarized here are the answers:
- "adxv" http://www.scripps.edu/~arvai/adxv.html<http://www.scripps.edu/%7Earvai/adxv.html> Run it with the option "-nopixmap" if you are using it inside an NX client - - There is also BDXV: an open-source viewer for ADSC-style *.img files being developed by the BSCB here at ALS: http://bcsb.als.lbl.gov/wiki/index.php/BDXV You will need GTK installed for this to work. - imosflm works very nicely indeed on windows, and needs no third-party package. - use idiffdisp - As I recently learnt from Andy Arvai, the "-nopixmap" is not needed if the (free) NX server has AGENT_EXTRA_OPTIONS_X="-defer 0" in its node.conf . - I think its's basically a TIF format and any program should work. I am using photoline32.
