FD2BSL - Conversion of LSQINT output files to BSL/OTOKO format
FD2BSL performs the conversion from the ASCII LSQINT (or FDSCALE) output files to BSL/OTOKO format allowing flexibility in the output image dimensions and I/SIGMA(I) cutoffs for intensity rejection. The output file has one raster per layer line and a user-defined number of pixels per raster. For Bragg-sampled data, the intensity of a reflection is divided by its multiplicity so that a representation of the cylindrical average of the squared molecular transform is given.
Keyworded input can be either upper or lower case. Only the first four characters of the keyword are required (and read). When values are input, they can take integer, real or exponent fields. Comments are signalled by ! and can occur anywhere on a line. Up to five continuation lines are allowed using & at the end of the current line. Lines must be less than 132 characters. Descriptions of the keywords recognised by FD2BSL are given below.
(Sub-keywords are indented on the line following the main keyword)
FILE - the program will now prompt for an input filename
PIXEls - one value to follow, the number of pixels in the BSL output file
RASTers - one value to follow, the number of rasters in the output BSL file
(N.B. The above two keywords can appear on the same line in any order)
(defaults: PIXELS 128 RASTERS (number of input layerlines))
RESOlution - two values to follow, the minimum and maximum d-spacings to be transformed
(Defaults: RESOLUTION 0.0 (max. resolution in dataset))
SIGMa - one value to follow, the minimum standard deviation for inclusion in the BSL output file
(Default: SIGMA 1.5)
RUN - begin transformation
