  573   Tue Nov 29 23:19:06 2016 Abhishek RajputPotential Incorrect Timing Calibration for DRS4 DataHello Stefan,

Thank you for the excellent explanation
and diagram. This part of the code is now
  
  572   Mon Nov 28 22:28:34 2016 Randall GladenLong timing between two channelsI don't believe I fully understand
how the timing works between multiple channels
on DRS4 board, even after reading the manual,
  
  571   Mon Nov 28 16:52:38 2016 Stefan RittPLL did not lockHave you tried to unplug and re-plug the
board a few times? According to our database,
you should have three boards. Do all three

about two years old, and it might be in use
(but I do not know exactly).
  
  569   Thu Nov 24 13:24:26 2016 Stefan RittPotential Incorrect Timing Calibration for DRS4 DataThe code in the macro is correct. The misconception
lies in the definition what "sample
0" means. Please view the attached picture.

  568   Thu Nov 24 08:13:23 2016 Stefan RittPLL did not lockWhich serial number has the board? Has
it been in use before or is it a new board?

  567   Thu Nov 24 00:40:38 2016 Alexey LubinetsPLL did not lockHello, everybody!

I installed DRSosc and DRScl. Command

I was running through a particular
binary file containing data taken on all
  
  565   Mon Nov 21 14:13:32 2016 Stefan RittChannel offsets in GetTime()Cell 700 is arbitrary. You can choose any
cell to align the channels to each other.
The only requirement is that it's always
  
  564   Fri Nov 18 16:38:42 2016 Gerard MontarouLabViewHello,

Did you start to write some VI
to interface DRS4board with labview ?
  
  563   Fri Nov 18 05:52:45 2016 Kurtis NishimuraChannel offsets in GetTime()Hello,

I have a question about the GetTime()
method in DRS.cpp.  I understand how

  562   Thu Nov 10 22:07:40 2016 Stefan RittBreak Statements in DRS4 Binary to ROOT MacroYou're right, fread() return the number
of objects read, so indeed it should be one
if successful.
  
  561   Thu Nov 10 20:54:45 2016 Christian FarinaMissing HeaderHi Stefan,

I have already read the paper.
I was just unsure where the calibration code
  
  560   Thu Nov 10 19:24:52 2016 Abhishek RajputBreak Statements in DRS4 Binary to ROOT MacroHello,

I am wondering why the code should
be changed to i < sizeof(eh), since doesn't
  
  558   Thu Nov 10 09:56:04 2016 Stefan RittBreak Statements in DRS4 Binary to ROOT MacroHi,

fread() returns the number of bytes
read and zero (I believe) if there is an
  
  557   Thu Nov 10 04:41:24 2016 Abhishek RajputBreak Statements in DRS4 Binary to ROOT MacroHello,

I recently modified the binary
to ROOT convertor written by Stefan (https://midas.psi.ch/elogs/DRS4+Forum/361)
  
  556   Wed Nov 9 19:49:07 2016 Stefan RittMissing HeaderBest is to read this paper: https://arxiv.org/abs/1405.4975

The source code for that is in
DRS.cpp in the DRS software distribution
  
  555   Wed Nov 9 17:19:48 2016 Christian FarinaMissing HeaderThank you Stefan, that was just what I
needed.

Also, I have another question,
  
  554   Tue Nov 8 10:20:52 2016 Stefan RittMissing HeaderThe web page from where you downloaded
the software contains a sentence "requires

I am completely new to this, so
