In what order are datasets processed in the pipeline?
In the Unix environment OPUS uses the glob command to determine what is waiting to be processed. For better performance, by default, OPUS uses the “no-sort” option of glob so that filenames are returned in no particular order. Thus it is difficult to determine which observation will enter the pipeline first if there are many candidates. To force the use of the sort option of glob, set an environment variable in your login shell or OPUS_DEFINITIONS_DIR:opus_login.csh file for setenv OPUS_SORT_FILES This will cause OPUS to perform all file searches using the sorted glob (which collates in LC_COLLATE order, see your operating system documentation for more information). This likely will result in alphabetically ordered searches.
