Transform UnpDataChunks into RawDataChunks for Calorimeter Research and Debugging

This document describes the process of transforming UnpDataChunks into RawDataChunks, part of the v00-03-00 unpack_reco package (not included in any DØ release). It outlines dependencies such as creating the UnpDataChunk in advance and integrating necessary components for calorimeter data processing, emphasizing adjustments like threshold settings and troubleshooting common error messages. Key changes in naming conventions and file management are also addressed, along with instructions for using the PackReco program effectively.

Presentation Transcript

  1. Raw Data Builder • Package to transform UnpDataChunks into RawDataChunks. • In v00-03-00 of unpack_reco (not in any DØ release) • pack_reco • requires the UnpDataChunk to be made first (duh) • calunpdata/CalMCToUnpReco • smtraw/SmtData2RawUnp • muo_unpdata/MuoMCToUnpReco • Been demonstrated to work producing both separately, and all together in one file: • CAL_FE • MUO_FE • SMT_FE • And there was much rejoicing.....

  2. How to Build a Calorimeter RDC • packages: • unpack_reco: v00-03-00 • calunpdata: v00-03-01 • caldata: head • t85 good for everything else (t86 had build problems on IRIX) • add PackReco.x to unpack_reco/bin/BINARIES • gmake unpack_reco.lib, unpack_reco.bin • adjust thresholds (default set to 0.001 GeV) in calunpdata/CalMCToUNPReco.rcp • copy framework rcp file (“PackReco_fwk.rcp”), and run configuration file (“cfg.dat”) from unpack_reco/bin to executable directory. • copy ReadEvent.rcp, WriteEvent.rcp to rcp directory • run PackReco.x -rcp PackReco_fwk.rcp

  3. Notes for Unpacker Coders • We’ve seen a lot of error messages like: • ERROR: UnpDataChunk::createModuleList() • factory was unable to create a module of type XXX mode YYY • This is because the module factory isn’t aware of the type of module that you’re asking for. It’s made aware of it via a registration macro that is found in the appropriate unpack_xxx_fe header file. Which means that this header needs to be included somewhere. • Best place to put it: framework registration source file for your MC  UDC code. • This means that people who use your MC  UDC package won’t have to bother you (me) when they can’t figure out why their program isn’t working.

  4. Changes in calunpdata Package • Naming convention of programs in calunpdata package sucks. It’s been very confusing. • New scheme: • CalPacked2RawReco  CalMCToUnpReco • CalRaw2PackedReco  CalUnpToMCReco • same thing for the framework registration macros, and rcp files • Also have replaced the debug flag with a debug_level rcp parameter. 0 means no debug info printed. • Someone from calorimeter group needs to tell me if the Gain table is accurate, and what’s the deal with: • [11,18,17] • [10,18,16] No electrical address translation • [9,18,16] but exist in gain table (and in MC). • [8,18,15]
