I think I understand what you want to do, but not how you have been
doing it. You have created a private repository based on an early
version of the BCI2000 code, made you own modifications, then merged
subsequent changes from the official BCI2000 repo into your own? I
didn't know you could do cross-repository merges.
As for the ranges, you have the order correct, but you are trying to
reference the tag in a revision where it was not yet created. Ignoring
the cross-repo question, this is what I think you need to do:
You have merged all their changes up to old trunk r2960, and you want
to merge everything that has happened since then. So the change set
you are merging is from old-trunk r2960 to new-trunk HEAD. The snag
here is that I don't know how to specify old-trunk r2960. On the
command line you can use a peg revision to specify it as
"tags/bci2000.v2.1_at_HEAD" which means "trace back the history of the
path which is tags/bci2000.v2.1 in the HEAD revision". You might get
away with putting trunk at r2960, and hope that it will use the path
that was called trunk in r2960 as opposed to r2960 of what is now
