hello,

maybe, dlRecord

http://www.desy.de/~dmitrov/Record/dlRecord/dl_doc.htm
Unfortunately, this description is too old and there is no information about
the CALCULATION conversion... We have to update it.
This is the list of all possible conversions:
NO CONVERSION - :);
LINEAR - the copy of the conversion in aiRecord for each element of the
array;
LINEAR+VEFF - the same plus the effective value calculation;
VEFF-  the effective value calculation (from raw data);
FFT - fft;
AVERAGE - the average value calculation;
CALCULATION - some kind of the calcRecord for arrays (for each element);
PARTIAL SUM, CORRELATION, TRANSIENT, SELECTION - specific conversions for
usage at DESY.

cheers,
Alexei
