There are two flux tree.
I guess flux;1 is correct because it behaves correctly when trueinfo turned on or off. So flux;2 should be removed

in code banks/src/evio2root.cc, "write_raws" will turn on raws bank entries like "pid,mpid,..." for all banks and by default it's on
This create a lot of entries in all banks.
generally flux bank wants those entries to show information, but any customized banks may not want those.
It's better to be able to turn on/off those entries for each bank individually.
The desired default behavior is on for flux and off for any other banks.

in file banks/src/fluxHistos.cc

The old name var1, var2,var3, ... var9 don't match new gemc name userVar001,userVar002...
So the header tree won't have those entries after conversion
We could either change banks to new name or change gemc back to old names.

Also new gemc can do any number of uservar, so banks need a way to do any number of uservar also.

If a bank is not found with the -B option evio2root should return error.

For example, I use flux bank with true info, but for other banks I only want customized defined bank. Now the default behavior is turn all banks on or off at same time, which create large file size and sometime problem if a customized bank has an entry with same name like true info.

all entries like pid in generated tree has type vector, even though it's supposed to be vector when gemc produces them in evio. My guess the conversion happens in evio2root.
Look at something line 100 of https://github.com/maureeungaro/banks/blob/master/1.2/src/banks.cc
It seems the int type should be treated correctly.
I am not sure this means some problem deeper
