NAME

X-GEN - x2u  

SYNOPSIS

x2u [frange]  

DESCRIPTION

"x2u" converts the output of DENZO into an X-GEN UREFLS file. The program reads a set of ".x" files, whose names are listed in a file with environment variable XINDEX; it writes to a file with the environment variable name UREFLS.

"x2u" begins by converting all the reflection data in each of the .x files specified into a typical UREFLS-style data structure. It then goes back through those structures and merges together data from reflections that appear in several consecutive images, taking the total intensity to be the sum of the intensities in the individual images. Partials found in the first and last images of the dataset are likely to be under-measured, since part of their profiles are missing. Accordingly it would be wise to omit those during the "reduce" step that follows. Thus if you have data from images 1 through 49, run reduce in the following way:

reduce -a2,48

so that the data from the incomplete frames are omitted from the resulting MULTIREF.

frange Specify the maximum number of images we expect any one reflection
will appear in. By default, this value is 16.
 

EXAMPLES

x2u 7
Convert all the .x files specified in XFRAMES to a UREFLS file, making the assumption that no reflection is more than 7 images wide.
