findhkl: Locate a specific reflection in all images on disk

The "findhkl" program can scan the disk for frames, locating a particular reflection or its symmetry relatives.

Usage

The program is invoked by the command line:

findhkl [options] [.x or .rmat file]

One ".x" or ".rmat" file can be specified to enable the program to find the orientation matrix for the crystal. If no file is specified, one is chosen from the current directory.

The program accepts all options for controlling the way the unit cell is treated, plus:

hkl=h,k,l: Specifies a reflection to find. Multiple "hkl=" options can be given.
fhkl=h,k,l: Specifies a floating-point reflection to find (with non-integer indices). Multiple "fhkl=" options can be given. If an "fhkl" reflection is given, no symmetry expansion is performed by findhkl.
display: If the "display" option is given, the frame in which the first reflection is found is displayed using ndisp.
display=#: If the "display=#" option is given, the first # hits will be shown in using ndisp. The special form "display=all" will go on to the end of the search. Between hits, the program will pause asking you (in a window) whether or not to continue with the search.
