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

  2784   03 Jul 2024 Tam Kai ChungBug ReportFail to build in the examples/experiment
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

  2856   22 Sep 2024 Tam Kai ChungBug ReportCan we convert the .mid file into .root file
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
  3068   14 Aug 2025 Tam Kai ChungForumHow can I retrieve online data
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

Dear K.O.
I would like to create some online plots (also reading the mid) when the frontend code is running. I may try to break the task into small steps first.
In the frontend.cxx, I have a bank called "TDC0" which includes an array of integer. The code is as follow:

bk_create(pevent, "TDC0", TID_INT, (void**) &pdata);
for(int i =0; i<ch; ++i)
*pdata++ = data[i];
bk_close(pevent,pdata);

In the meantime, I want to run manalyzer to get some plots.
  2125   05 Mar 2021 Svetlana ChesnevskayaBug ReportNew MIDAS old frontend incompatibility
Hello!

Could you help me solve the problem of compatibility between our frontend (created in 2017) and the fresh MIDAS? The old MIDAS (2017) worked well, then we did not use it.
While compiling the frontend, I get a lot of warnings and a few compilation errors.

Any help will be greatly appreciated.

Thanks in advance.
With the best regards,
Svetlana

  87   25 Nov 2003 Suzannah Daviel delete key followed by create record leads to empty structure in experim.h
Hi,

I have noticed a problem with deleting a key to an array in odb, then
recreating the record as in the code below. The record is recreated
successfully, but when viewing it with mhttpd, a spurious blank line
(coloured orange) is visible, followed by the rest of the data as normal.

This blank line causes trouble with experim.h because it
produces an empty structure e.g. :

#define CYCLE_SCALERS_SETTINGS_DEFINED

typedef struct {
  struct {
  } ;
  char      names[60][32];
} CYCLE_SCALERS_SETTINGS;

rather than :

#define CYCLE_SCALERS_SETTINGS_DEFINED

typedef struct {
  char      names[60][32];
} CYCLE_SCALERS_SETTINGS;


This empty structure causes a compilation error when rebuilding clients that
use experim.h

SD



 CYCLE_SCALERS_TYPE1_SETTINGS_STR(type1_str);
 CYCLE_SCALERS_TYPE2_SETTINGS_STR(type2_str);

Both type1_str and type2_str have been defined as in
experim.h
i.e.
#define CYCLE_SCALERS_TYPE1_SETTINGS_STR(_name) char *_name[] = {\
"[.]",\
"Names = STRING[60] :",\
"[32] Back%BSeg00",\
"[32] Back%BSeg01",\
 ........
 ........
"[32] General%NeutBm Cycle Sum",\
"[32] General%NeutBm Cycle Asym",\
"",\
NULL }

#define CYCLE_SCALERS_TYPE2_SETTINGS_STR(_name) char *_name[] = {\
"[.]",\
"Names = STRING[60] :",\
"[32] Back%BSeg00",\
"[32] Back%BSeg01",\
...........
............
"[32] General%B/F Cumul -",\
"[32] General%Asym Cumul -",\
"",\
NULL }

  if (db_find_key(hDB, 0, "/Equipment/Cycle_scalers/Settings/",&hKey) ==
DB_SUCCESS)
    db_delete_key(hDB,hKey,FALSE);
          
  if (  strncmp(fs.input.experiment_name,"1",1) == 0) {
      exp_mode = 1; /* Imusr type - scans */
      status =
db_create_record(hDB,0,"/Equipment/Cycle_scalers/Settings/",strcomb(type1_str));
    }
  else {
    exp_mode = 2; /* TDmusr types - noscans */
    status =
db_create_record(hDB,0,"/Equipment/Cycle_scalers/Settings/",strcomb(type2_str));
  }
  510   20 Oct 2008 Suzannah DavielBug Reportcustom web pages: customscript buttons and start/stop buttons generate errors
I am using an external Custom web page via a link in the ODB in /Custom, and
Javascript to add customscript button(s) and run start/stop buttons.

After executing these buttons, instead of returning to the custom page, or
to the Midas main status page, there is an error page generated:

Invalid custom page: NULL path
and the URL is 

http://lxfred:8082/CS/

The behaviour is the same whether the custom page replaces the main status page
or not.

I am using
MIDAS version 2.0.0
mhttpd.c SVN Rev 4282

In an older version of mhttpd.c, buttons of this type used to return to the
Midas main status page regardless of whether the custom page replaced the status
page. I found this behaviour annoying, and I made a custom mhttpd.c that
returned to the custom page. 
Would it be possible to fix this problem, and to return to the custom page after
pressing the buttons?


Here is the Javascript to add the buttons:

<script type="text/javascript">
var rstate = '<odb src="/runinfo/run state">'

 if (rstate == 1) // stopped
    document.write('<input name="cmd" value="Start" type="submit">')
 else if (rstate == 2 // paused
    document.write('<input name="cmd" value="Resume" type="submit">')
 else  // running
 {
    document.write('<input name="cmd" value="Stop" type="submit">')
    document.write('<input name="cmd" value="Pause" type="submit">')
 }

 if (rstate == 1) // stopped
    document.write('<input name="customscript" value="tri_config" type="submit">');
</script>
  522   04 Nov 2008 Suzannah DavielSuggestion<odb ... edit=1> buttons and javascript 
When writing custom webpages, it would be nice to be able to write code such as

<odb src="/Equipment/TITAN_ACQ/ppg cycle/trans3/time offset (ms)" edit=1>

from Javascript, e.g.
<script  type="text/javascript">
if ( flag != 3)
   document.write('<odb src="/Equipment/TITAN_ACQ/ppg cycle/trans3/time offset
(ms)" edit=1>ms');
else
   document.write('<odb src="/Equipment/TITAN_ACQ/ppg cycle/trans4/time offset
(ms)" edit=1>ms');
</script>

This is not translated correctly by mhttpd; the final quote and bracket get
stripped off, and it gives Javascript error

 Error: unterminated string literal
Source File: http://titan04:8089/CS/ppg_cycle?cmd=Edit&index=11
Line: 477, Column: 18
Source Code:
   document.write('<input type=text size=10 maxlength=80 name=value value="1">

I can get round this by using an input box and a combination of ODBGet and
ODBSet, but it would be easier if the edit=1 form above worked correctly, or
there was a command like ODBSet that would accept input from the user.

Thanks.

 would be nice is there was a command such as ODBGet or ODBSet that would work
with javascript to
  561   27 Jan 2009 Suzannah DavielForumQuestion - ODB access from a custom page
At present the only documentation on the Javascript library is in this elog
e.g. Message 496 31 Jul 08

The Javascript library which you can view
http://<your mhttpd host>/mhttpd.js
now supports ODBEdit as well as ODBGet and ODBSet
 
I advise you get the latest version of mhttpd.c so you can use ODBEdit which changes
the ODB value directly via ODBSet.

You use it like this:
document.write('<a href="#" onclick="ODBEdit(/Equipment/test/Variables/Demand[0])">');
document.write('<odb src="/Equipment/test/Variables/Demand[0]">');
document.write('</a>');

You can also use HTML to edit the variables, but the advantage of Javascript is that
you can use variable ODB paths, so it is more powerful.

Here is an example of using a form on a custom page to edit a variable (in the
example, the run number) using Javascript (ODBEdit) and HTML. 

To try this example, in ODB, create key (STRING)
/custom/try& 
 and set it to "/home/user/try.html"

where the path of the example code on the disk is  /home/user/try.html

This will put an alias link on the Main Status page called "try" which you click on
to see the custom page.

Code of try.html:

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 TRANSITIONAL//EN">
<html><head>
<title> ODBEdit test</title>
<script src="/js/mhttpd.js" type="text/javascript"></script>

<script type="text/javascript">
var my_action = '"/CS/try&"'
var rn
var path

document.write('</head><body>')
document.write('<form method="get" name="form2" action='+my_action+'> ') 
document.write('<input name="exp" value="'+my_expt+'" type="hidden">');

document.write('Using Javascript and ODBEdit:
')
path='/runinfo/run number' 
rn = ODBGet(path)
document.write('Run Number: '+rn+'

document.write('Edit Run Number:')

Using HTML :


Using edit=2 ...  Run Number:
<odb src="/runinfo/run number" edit=2>


Using edit=1 ...  Run Number:
<odb src="/runinfo/run number" edit=1>


</form>
</html>


Note the "edit=2" feature is handy so that you can use Javascript or HTML on your
page and the user sees no difference.

Would you consider using a different colour for the alias buttons (or background
colour)? At present it's hard to know whether a button is an alias link, a custom page
link or a user-button especially if you are not familiar with the button layout.
  693   27 Jan 2010 Suzannah DavielForumcustom page - flashing filled area
Hi,

On a custom web page, can a "filled" area be made to flash (i.e. cycle between 
two colours)? This area would have to update faster than the whole page update.
 
I have a custom page representing a gas system, and the users
want the heaters to flash when they are on, as is done in their EPICS page.

Thanks,
Suzannah

Thank you - I have added it to the documentation.
  1349   08 Mar 2018 Suzannah DavielSuggestionlink to an array element displays whole array in mhttpd
A link to an array variable such as

[local:npet:Stopped]/>ls /rcparams/ControlVariables/
TRFC:PB5 (V) -> /Equipment/Beamline/Variables/Demand[56]
                                17835

displays the whole Demand array on the mhttpd ODB page (see attachment)
rather than just the one element Demand[56].
This behaviour also occurs with older versions of mhttpd.
 
Not sure if it's a bug or a feature, but my suggestion is that it
ought to display the one element only (as odbedit does) and not the whole array.

  1350   09 Mar 2018 Suzannah DavielBug Reportlink to an array element displays whole array in mhttpd
Further to my last message, I see that a midas version from 2013 does indeed display
links to arrays as I would expect (see attachment). Therefore the problem in later
versions  is a bug rather than a feature.

Thank you. That has solved the problem.
