[subexp-daq] Question on UCESB

[Weber, Guenter Dr.]

Dear Håkan,


next thing is that we would like to teach the HBOOK part to work with 64-bit uints (to not have the timestamp as two 32-bit words). We noticed there is a pearl script: make_external_struct_sender.pl

Is this an integral part that we would need to touch?




Best greetings

Günter

Nice that it worked.

I think the only 'easy' way to avoid the '..._nI' entries is to not use
zero-suppression for the array.

However, then it would/should appear fully in all events.  Since the
scaler module might not always be read, it would then contain the value 0
when nothing filled the array for that event.  That may (or not) be more
confusing.

Cheers,
Håkan
