+\subsection da_ss1 Pedestals
+
+The syntax is: MUONTRKPEDda.exe "raw data file"
+
+Two input files located in the DAQ Detector database (DetDB) are needed:
+
+- muontrkpedvalues is built in flight in CONFIGURATION_PED.sh (ECS script) and contains one parameter "config" :
+ config = 1 if configuration file has to be used (OnLine case)
+ config = 0 if not (OffLine case for the time being)
+
+- config_ldc-MTRK-S3-0 : configuration file name corresponding to MuonTracker Station 3 if (for example) DA is running on ldc-MTRK-S3-0
+
+- DA validation: see Header of MUONTRKPEDda.cxx for reference run, and corresponding input mutrkpedvalues and configuration files are located in path=/afs/cern.ch/user/j/jcharvet/public/DA_validation
+
+\subsection da_ss2 Electonics gain
+
+The syntax is: MUONTRKGAINda.exe "raw data file"
+
+Two input files located in the DAQ Detector database (DetDB) are needed:
+
+- muontrkcalibvalues: which attributes to each run index (1->11) its corrresponding DAC value. The other parameters are used to tune the fit procedure (for expert). The last parameter indicates the number of events to be read: if "0" all events in the run are read, if not the parameter indicates the maximum number of events to be read.
+Default values are listed below

+\section da_s3 Using the DA Offline
+
+The DAs normally runs with a RAW data DATE format as input
+The development of an Offline version is under way.
+
+Nevertheless, Pedestal runs can be analysed locally, but without detector configuration file. If you get a file in root format (e.g. from alien), you can de-rootify it using the
+ "deroot" program which is part of aliroot.
+Note that PED and GAIN DAs work with ROOT input files as well.
