Hi Hunter 

This sounds like a Triumf specific problem; 
not a MIDAS problem.  Please email me directly 
and we can try to solve this problem.

Dear MIDAS users,

We would like to arrange another MIDAS workshop, following on from previous successful workshops in 2015, 2017 and 2019.  The 
goals of the workshop would include:

- Getting updates from MIDAS developers on new features and other changes.
- Getting reports from MIDAS users on how they are using MIDAS, what is working and what is not
- Making plans for future MIDAS changes and improvements

This would be a one-day virtual workshop, planned for about 4 hours length.  The workshop will probably be after another of 
Stefan's visits to TRIUMF.

If you would be interested in participating in such a workshop, please help us choose the date by filling out this doodle poll:

https://doodle.com/meeting/organize/id/dBPVMQJa

Please fill in the poll by June 9, if you are interested.  We will announce the date soon after that.

Thanks,
Thomas

Hi All,

Thanks to everyone who filled out the doodle poll.  

Based on the results we will plan to have this workshop on September 13, at 9AM-1PM (Vancouver) / 6PM-10PM (Geneva).  Apologies to 
those for whom this is a bad time/day; in particular for MIDAS users in Asia.

If you would like to present a report at the workshop on your experiment's MIDAS experience, then please email me (lindner@triumf.ca).  
It would be great to know this in advance so that we can start preparing an agenda.  Feel free to also email me if there are topics 
that you would like addressed at the workshop.

Thanks,
Thomas

Dear All,

A quick update on the MIDAS workshop.  Based on the number of planned talks we have made the decision to switch to a two day workshop on Sept 12 and 13 
(rather than just Sept 13).  We decided 4 hours was not enough time to hear all the reports and have fruitful discussions; having a much longer meeting 
on a single day was a bad idea given the time zones involved.

We have a tentative agenda planned for the workshop, which you can see here:

https://indico.psi.ch/event/15025/timetable/

We are still confirming some talks, so the agenda may still change a bit.  But the baseline plan will be that the workshop will be 

8:30AM-12:30PM (PDT) / 5:30PM-9:30PM (CEST)

on Sept 12-13.  We hope that these times still work for everyone planning to attend.

Cheers,
Thomas

Dear All, 

A final reminder about the MIDAS workshop in 6 days.  A (hopefully) finalized agenda is posted here:

https://indico.psi.ch/event/15025/timetable/

In the overview section of the indico page you will find the zoom link for the workshop.

We plan for the workshop to have a lot of time for discussion. This means that the exact schedule of the workshop is a little uncertain; hence the actual start 
time of each talk will also have some uncertainty.  We have scheduled that each day's session will be around 3.5 hours, but it is possible that the sessions will 
be a little longer in reality.  Stefan and Pierre will try to ensure that we stay roughly on schedule.

Looking forward to seeing people there.

Cheers,
Thomas

Hi,

Sorry, we have been slammed with a couple projects on the TRIUMF side in the past weeks and haven't found time for a 
response.  I am hopeful that we will be able to answer this question (and the cache size question) within the next 10 
days.  

Again apologies,
Thomas

Dear MIDAS enthusiasts,

We are planning a fifth MIDAS workshop, following on from previous successful 
workshops in 2015, 2017, 2019 and 2023.  The goals of the workshop include:

- Getting updates from MIDAS developers on new features, bug fixes and planned 
changes.
- Getting reports from MIDAS users on how they are using MIDAS and what problems 
they are facing.
- Making plans for future MIDAS changes and improvements

We are planning to have an online workshop on Sept 22-23, 2025 (it will coincide 
with a visit of Stefan to TRIUMF).  We are tentatively planning to have a four 
hour session on each day, with the sessions timed for morning in Vancouver and 
afternoon/evening in Europe.  Sorry, the sessions are likely to again not be well 
timed for our colleagues in Asia.  

We will provide exact times and more details closer to the date.  But I hope 
people can mark the dates in their calendars; we are keen to hear from as much of 
the MIDAS community as possible.  

Best Regards,
Thomas Lindner

Dear all,

We have setup an indico page for the MIDAS workshop on Sept 22-23.  The page is here

https://indico.psi.ch/event/17580/overview

As I mentioned, we are keen to hear reports from any users or developers; we want to hear  
how MIDAS is working for you and what improvements you would like to see.  If you or your 
experiment would like to give a talk about your MIDAS experiences then please submit an 
abstract through the indico page.  

Also, feel free to also register for the workshop (no fees).  Registration is not 
mandatory, but it would be useful for us to have an idea how many people will connect.

Thanks,
Thomas

Dear all,

A reminder we will have our MIDAS workshop starting two weeks from today (Sept 22-23).  The 
meeting will be in the morning in Vancouver, evening in Europe.  A detailed schedule is available 
here

https://indico.psi.ch/event/17580/timetable/#20250922.detailed

The zoom link is available from the indico overview page. The schedule will allow for a fair bit 
of discussion time, so it is unlikely that talks will start exactly on time.

Looking forward to seeing people there.

Thomas

Dear all,

The original zoom link on the indico page was not correct.  We have created a new zoom link and updated the 
Indico overview page.  Please refresh the Indico overview page to get the correct link.

Documenting a discussion I had with Konstantin a while ago.

One aspect of the MIDAS history plotting I find frustrating is the sequence for adding a new history 
variable and then plotting them.  At least for me ,the sequence for a new variable is:

1) Add a new named variable to a MIDAS bank; compile the frontend and restart it; check that the new 
variable is being displayed correctly in MIDAS equipment pages.

2) Stop and restart programs; usually I do
- stop and restart mlogger
- stop and restart mhttpd
- stop and restart mlogger
- stop and restart mhttpd

3) Start adding the new variable to the history plots.

My frustration is with step 2, where the logger and web server need to be restarted multiple times.  
I think that only one of those programs actually needs to be restart twice, but I can never remember 
which one, so I restart both programs twice just to be sure.

I don't entirely understand the sequence of what happens with these restarts so that the web server 
becomes aware of what new variables are in the history system; so I can't make a well-motivated 
suggestion.

Ideally it would be nice if step 2 only required restarting the mlogger and mhttpd automatically 
became aware of what new variables were in the system.

But even just having a single restart of mlogger, then mhttpd would be an improvement on the current 
situation and easier to explain to users.

Hopefully this would not be a huge amount of work.

I assume that mlogger rescanning ODB is somewhat intensive process; and that's why we don't want rescanning to 
happen every time the ODB is changed?

Stopping/restarting mlogger is okay.  But would it be better to have some alternate way to force mlogger to 
rescan the ODB?  Like an odbedit command like 'mlogger_rescan'; or some magic ODB key to force the rescan.  I 
guess neither of these options is really any easier for the developer.  It just seems awkward to need to restart 
mlogger for this.

It would be great if mhttpd can be fixed so that it updates the cache when history editor is opened.

This seems like a reasonable plan to me (combined with clear documentation).

Dear experts,
I am a new user of MIDAS. I try to follow the instruction from 
https://daq00.triumf.ca/MidasWiki/index.php/Quickstart_Linux
to install MIDAS in Fedora 39.

When I try to have a try in the section of "Clients run on Localhost only"
https://daq00.triumf.ca/MidasWiki/index.php/Quickstart_Linux#Clients_run_on_Localhost_only

I get the error of "undefined reference to" several variables in the mfe.cxx. For example the variable "max_event_size_frag". May I know any idea about this issue? Thank you.


Best,
Terry

Hello Nick,
I am using the most updated tag: midas-2022-05-c-1284-g4a77127b.

Here would be some of the examples of the error listed:
/usr/bin/ld: /packages/midas/lib/mfe.o: in function
/usr/bin/ld: /packages/midas/src/mfe.cxx:2537: undefined reference to `event_buffer_size'
...
Also several undefined reference. Any idea about it? Thank you.

Best,
Terry

Dear experts, 
I am a new user of MIDAS. I have just created some banks by a frontend.cxx code.
Now, I would like to do some analysis from the data.

I have an analyzer.cxx code (A very simple one without complicated routine).

I try to link the analyzer.o with rmana.o and libmidas.a to create analyzer.exe

I am not sure whether I can do the analysis offline in the follow way:

analyzer.exe -i run00001.mid -o run00001.root

When I run this command,  I get the following error:

Error in <TClass::LoadClassInfo>: no interpreter information for class TSocket is available even though it has a TClass initialization routine.

I am using root 6.30

Any suggestion about this issue? Thank you.

Best,
Terry

Dear experts,
I would like to know how to retrieve the online data during the experiment so 
that I can create my own custom plot. I execute my own frontend.exe to start the 
experiment. I can get a midas file after the experiment, but I am not sure about 
how to retrieve the online data. I know that rootana can help us to get the 
online plots, but the instructions in rootana is not clear. Can anyone give me 
some suggestion?  Thank you.

Best,
Terry
