Raw data may be converted into ROOT format in following way:

  1. Go4 library must be available. One of the well working possibilities is to use library created by Egor Ovcharenko. It can be downloaded here. Compilation is performed by bash script "compile.sh". Some play with environment variables is needed. See *.sh scripts. README file will be created.
  2. Compiled "libUserAnalysis.so" library must be in folder with data to be converted. The use of symbolic link is possible.
  3. Conversion of data is performed by command
    go4analysis -v -lib libUserAnalysis.so -file INPUTFILENAME
    in folder with treated raw files. INPUTFILENAME is file with raw data either in lmd or lml format.
  4. The output is saved in "output.root" file. This option is probably hardcoded in Go4 library source and will be modified. The "output.root" should be renamed otherwise it will be replaced by new converted data.
