auto merge doesn't work

[WeissShahaf]

is Ironclust still being maintained?
i've been using ironclust since it came out. and very happy overall.
some things are still broken though.

-Phy IO is not funcitonal. maybe because of changes to kilosort over the years. but been this way at least since kilosort2
-irc2, never worked for me. it runs, but in the gui cannot merge or split.

most crucial for me:
**-with irc manual *.prm (non irc2), auto merging crashes. ERROR:

I think this is due to one of the variables not being updated when clusters are split/merged/deleted:
S_clu.nClu
S_clu.cviSpk_clu
