|
Hello,
I tried different ways to pass parameters to bash script, but there are seems to
be empty, what could be the problem?
We have seuqencer like
ODBGET "/Runinfo/runnumber", firstrun
LOOP n,10
#changing HV
TRANSITION start
WAIT seconds,300
TRANSITION stop
ENDLOOP
ODBGET "/Runinfo/runnumber", lastrun
SCRIPT /.../script.sh ,$firstrun ,$lastrun
and script.sh like
firstrun=$1
lastrun=$2
Thanks. Alexey. |

Thanks. It works perfect.
Another question is:
Is it possible to run .msl seqscript from bash cmd?
Maybe it's easier then
1 odbedit -c 'set "/sequencer/load filename" filename.msl'
2 odbedit -c 'set "/sequencer/load new file" TRUE'
3 odbedit -c 'set "/sequencer/start script" TRUE'
What is the best way to have a button starting sequencer
from /script (or /alias )?

06 Nov 2020, Alexandr Kozlinskiy, Suggestion, cmake build fixes
|
hi,
there are several problems with current cmake build files in midas:
- not all systems have cuda libs in /usr/local/cuda
- not all cmake version like when redefining vars
(i.e. redefining ROOT_CXX_FLAGS)
- c++ standard not matching the one used to build ROOT
- ROOTSYS is not needed to find ROOT (it is enough to have root in PATH)
I have posted pull request 'https://bitbucket.org/tmidas/midas/pull-requests/17'
which tries to fix some of the problems.
Tests and comments are welcome. |

07 Jun 2017, Alberto Remoto, Forum, Increase MAX_EVENT_SIZE
|
Hello,
I am using a CAEN v1720 to digitise signal coming from 5 PMTs and I need to extend the read-
out window to 1ms.
Given the sampling frequency of 250 MHz, each event would consist of about 4.78 MB
Accordingly to the documentation I found in:
https://midas.triumf.ca/MidasWiki/index.php/Event_Buffer
- I modified the value of ODB /Experiment/MAX_EVENT_SIZE to 8 MB (I overestimated it in case
I will readout all 8 channels of the v1720)
- I modified the ODB key /Experiment/Buffer Sizes/SYSTEM to 512 MB (which allow to contain
about 100 events in the buffer)
The max_event_size in the frontend source code is set to 32 MB while the event_buffer size is
200 times the max_event_size. So I did not modify those values.
When I start a new run, the MIDAS crash and the ODB gets corrupted:
$ odbedit
[ODBEdit,ERROR] [odb.c:1134:db_open_database,ERROR] Different database format: Shared
memory is 262148000, program is 3
[ODBEdit,ERROR] [midas.c:2157:cm_connect_experiment1,ERROR] cannot open database
Unexpected error #326
Do you have any idea of what might be the problem?
The same thing happen if I reduce the buffer size to 128 MB.
The computer running MIDAS has 2 Quad CPU @ 2.83GHz and 4 GB RAM.
Thank you in advance for any help!

25 Aug 2024, Adrian Fisher, Info, Help parsing scdms_v1 data?
|
Hi! I'm working on creating a ksy file to help with parsing some data, but I'm having trouble finding some information. Right now, I have it set up very rudimentary - it grabs the event header and then uses the data bank size to grab the size of the data, but then I'm needing additional padding after the data bank to reach the next event.
However, there's some irregularity in the "padding" between data banks that I haven't been able to find any documentation for. For some reason, after the data banks, there's sections of data of either 168 or 192 bytes, and it's seemingly arbitrary which size is used.
I'm just wondering if anyone has any information about this so that I'd be able to make some more progress in parsing the data.
The data I'm working with can be found at https://github.com/det-lab/dataReaderWriter/blob/master/data/07180808_1735_F0001.mid.gz
And the ksy file that I've created so far is at https://github.com/det-lab/dataReaderWriter/blob/master/kaitai/ksy/scdms_v1.ksy
There's also a block of data after the odb that runs for 384 bytes that I'm unsure the purpose of, if anyone could point me to some information about that.
Thank you! |

All banks are aligned on a 8-byte boundary, so that one has effective 64-bit CPU access.
If you have sections of 168 or 192 bytes, this must be something else, like another bank (scaler event, slow control event, ...).
The easiest for you is to check how this events got created using the bk_create() function.
Best,

Upon further investigation, the sections I'm looking at appear to be clusters of headers for empty banks.
Thank you! |
