**-r** Base pairs added downstream (right of) of each entry in A when searching for overlaps in B. *Allows one to create assymetrical "windows". Default is 1000bp*.
**-sw** Define -l and -r based on strand. For example if used, -l 500 for a negative-stranded feature will add 500 bp downstream. *By default, this is disabled*.
**-sm** Only report hits in B that overlap A on the same strand. *By default, overlaps are reported without respect to strand*.
**-Sm** Only report hits in B that overlap A on the same strand. *By default, overlaps are reported without respect to strand*.
**-Sm** Only report hits in B that overlap A on the opposite strand. *By default, overlaps are reported without respect to strand*.
**-u** Write original A entry once if any overlaps found in B. In other words, just report the fact at least one overlap was found in B.
**-c** For each entry in A, report the number of hits in B while restricting to -f. Reports 0 for A entries that have no overlap with B.
**-v** Only report those entries in A that have *no overlaps* with B.
