Description
file
CDATA
None
A relative or absolute pathname.
For relative pathnames, the base directory is the $STUDY_DIR/drf
directory of the study.
The pathname must be specified using UNIX file and directory naming semantics.
If the pathname is not given, the processing system
will create a pathname from:
the base directory of $STUDY_DIR/drfof the
study followed by
the name of the batch, and terminated with
the fixed suffix, .drf
The pathname specification can also include a sub-folder, the basic rule is,
/STUDY_DIR/drf/sub-folder/xx_out.drf,
which starts from absolute path, or
sub-folder/xx_out.drf,
which is a relative path.
In both ways, the output file should be found in
/STUDY_DIR/drf/sub-folder/xx_out.drf.
The filename cannot contain ../ or /.. to alter the file path.
Doing this will lead to error.
Description
Records can be selected by a previously created DRF.
Each record in the DRF is retrieved and processed with the exception of
any secondary records which are omitted.
Secondary records are only used to link images to data records and can not be processed in batch.
