Historically there have been two options inthe [Zmap] stanza that controlled how ZMap started up and loaded data:
[ZMap] show-main-window = false default-sequence = chr6-18_12314500-12344230
This is a little clumsy and the following changes are introduced:
> zmap --start=1234500 --end=1244500 [human/]chr6-18
Note that the above implies that Otterlace will also include the dataset name eitehr in the sequence name or as a separate XML field.
