Hi Scott, it's complaining that the input files are not in the standard
CCP4 map format. Since they have the extension 'pdb' and not 'map' could
they by any chance be PDB format files? If so then this won't work!
Cheers

Hi all,
I tried using mapsig for the first time, and I got multiple errors (text
pasted at bottom). This is on mac os x 10.8.5, and the CCP4 install is
6.4.0. I followed these instructions to be able to use CCP4 programs at the
command line:

I have also tried the csh version as well, with the same results. Any
advice would be greatly appreciated. This is my first time attempting to
use CCP4 without the GUI, so if there's additional setup necessary, that
would be great info to know.
Thanks,
Scott

BE WARNED THAT THIS PROGRAM ASSUMES PERIODIC MAP BOUNDARIES,
(I.E. THE LEFT-HAND EDGE ABUTS ONTO THE RIGHT-HAND EDGE) AND
THEREFORE MAY NOT LOCATE PEAKS AT THE EDGES OF THE MAP
CORRECTLY IN OTHER CASES. IN SUCH CASES THE MAP SHOULD BE
EXPANDED IN ONE OR MORE DIRECTIONS TO MAKE IT PERIODIC IN ALL
DIRECTIONS.
