Thank you very much for this, Graeme. I must however that I have had some problems with ccmxmake. Firstly, the utility refuses to access the DTP-94 with 'new_disprd failed with "Instrument Access Failed" ' when using the '-N' switch to avoid having to remove the eye-one from the screen every testing round. Without using the '-N' switch the patches read, but the display window appears to hang randomly with the spinning egg-timer replacement, resulting in 15 measurement of the same patch. When the reading does complete, attempting to save the matrix results in the program crashing immediately, with no file saved. Have you any suggestions for what I could be doing wrong? I did get it to work once when I got a chance to try it quickly on Wednesday, but could not reproduce the success. The file seemed valid and plausible. On the more trivial matters, the ccmxmake -h text reads: 'usage: ccmxmake [-options] output.sp'. I presume this should read .ccmx? My usage is: 'ccmxmake -v -yl -d2 -F -N w2420.ccmx' Thanks again for this, Sam Berry www.satsumatree.co.uk On 8 September 2010 13:37, Graeme Gill <graeme@xxxxxxxxxxxxx> wrote: > > Version 1.3.0 includes a number of bug fixes, and a couple of new features: > > Added option to dispcal and dispread that attempts to counteract > instrument black drift and display white drift (-I option). > > Added option to dispcal to allow specifying a non 1931 2 degree > observer if a spectrometer is being used. > > Added new utility ccmxmake, which makes Colorimeter Correction > Matrices > for a particular Colorimeter + Display combination, using a > Spectrometer > as a reference.
