 ### Summary Statistics
 
 * `-t < $\theta$ >`: Set the mutation rate to $\theta = 4N_0u$, where _u_ is the neutral mutation rate per locus. If this options is given, scrm generates the segregating sites output.
+* `-transpose-segsites` or `--transpose-segsites`: If given, the segregating sites are printed with each row representing a mutation and each column representing a haplotype, rather than the other way round. Additionally, the time at which a mutation occurred is reported (in units of _4 * N0_ generations) [since v1.7.0].
 * `-T`: Print the local genealogies in newick format.
 * `-O`: Print the local genealogies in the `oriented forest` format as described in [Kelleher _et al._ (2014)](http://dx.doi.org/10.1016/j.tpb.2014.05.001) [since v1.2].
-* `-L`: Print the TMRCA and the local tree length for each segment (behaves different to ms).
+* `-L`: Print the TMRCA and the local tree length for each segment (behaves different to ms). Both values are scaled in coalescent time units, e.g. in _4 * N0_ generations.
 * `-oSFS`: Print the site frequency spectrum. Requires that the mutation rate $\theta$ is given with the '-t' option.
 * `-SC [ms|rel|abs]`: Scaling of sequence positions. Either relative to the locus length between 0 and 1 (`rel`), absolute in base pairs (`abs`) or `ms`'s scaling (default) where the positions in the _segregating sites_ output are relative, and the positions in the trees output are absolute (`ms`) [since v1.3.0].
