run_file_operation(outdoc, filenames, use_segment_table, operation, preserve=True)

source code 

Performs an operation (intersect or union) across a set of files. That is, given a set of files each with segment definers DMT-FLAG1, DMT-FLAG2 etc the result is a file where

DMT-FLAG1 = (file 1's DMT-FLAG1 operation file 2's DMT-FLAG1 operation ...) DMT-FLAG2 = (file 1's DMT-FLAG2 operation file 2's DMT-FLAG2 operation ...)

etc

run_segment_operation(outdoc, filenames, segments, use_segment_table, operation, result_name='RESULT', preserve=True)

source code  

Performs an operation (intersect or union) across a set of segments.
That is, given a set of files each with segment definers DMT-FLAG1,
DMT-FLAG2 etc and a list of segments DMT-FLAG1,DMT-FLAG1 this returns

RESULT = (table 1's DMT-FLAG1 union table 2's DMT-FLAG1 union ...)
         operation
         (table 1's DMT-FLAG2 union table 2's DMT-FLAG2 union ...)
         operation
etc
