META TOPICPARENT	name="HcalDTC"

New analysis code being developed for 2014 data format

Line: 25 to 25

The two options for file types processed by this code are binary and root files. The code to switch from one to another or vice versa is here:

Binary to Root: https://github.com/elaird/hcalraw (From Ted Laird)

Added:

First run make in the cpp folder

The main tool for making badcoffee binary files is hcalraw/cpp/badcoffee.cpp. Usage is cat a.dat | ./badcoffee fed#.

Root to Binary: http://edf.bu.edu/svn/edf/arcaro/cms/trunk/pythontools/rootdumper/ or http://edf.bu.edu/svn/edf/arcaro/cms/trunk/analyzer/dumpraw/

The dumpraw code is a cmssw analyzer and requires a cmssw environment. The rootdumper only requires root.
The rootdumper is built by running the Makefile in rootdumper/cpp.
- Run the code using ./oneRun.py --rootFile=HTB_007850.root --feds=928 --nEvents=101 --outputFile=data1.dat

The dumpraw analyzer can be built with the same directions as the CMSSW section below.

- Run the code using cmsRun .../python/ConfFile_cfg.py

Unpacker

Changed:

<
< Unpacker consists of three classes to parse AMC13 data format: FedEvent, FedBlock, and FedAMC. Various tools have also been created to utilize these classes and analyze the data. All code can be found here: http://edf.bu.edu/svn/edf/arcaro/cms/trunk/

Class documentation: http://ohm.bu.edu/~djarcaro/Documentation/unpacker.pdf

Line: 60 to 61

Unpacker histogram option

If root is installed dumptmp.cc can be made by $make root=1. dumptmp is identical to dump but also creates a root file with a histogram of the error array for easier visualization with large files.

CMSSW

The dump software has also been implemented in a cmssw analyzer to extract raw data from global/local root files and unpack it. This requires a cmssw environment (most likely lxplus). The code can be found here http://edf.bu.edu/svn/edf/arcaro/cms/trunk/analyzer/

and .../trunk/cmsswtools. General instructions to make an analyzer can be found here: https://twiki.cern.ch/twiki/bin/view/CMSPublic/WorkBookWriteFrameworkModule

Line: 73 to 76

$ scram b

Changed:

<
< To run the analyzer first set the parameters in the python file analyzer/parse/python/ConfFile_cfg.py. The most important parameters (besides the file name) are the HcalTBSource vs PoolSource and the rootType string input. Change these to correspond to either a local or global root file. The python script is set to run over multiple files in a directory. To then run the analyzer:

To Do List

Deleted:

<

Add a doxygen configuration file and "doc" target to makefile so one can do 'make doc' and get the doxygen output.

New Features

DONE:

In FedEvent::PreParse the expression if(GetNAMC() > 0 || GetNAMC() < 13) is always true. I think you mean to use && instead of ||.
In FedEvent::PreParse there are two possibilities for size: a) 2 and b) 4...14. It should throw an exception if any other value is passed. The comments should reflect this.

Check for consistency of LMSEPVC bits through an entire event
- MS should be "10" for first block, "11" for intermediate blocks, "01" for final blocks.
- C should be 1 when MS="01".
- EP should always be "11" I think
Check Blk_No, AmcNo, BoardID in block headers for consistency throughout event
Add option to dump entire AMC payloads
