Hi Mark, and Mark S.

>Can you open other plot windows in medm, e.g. the cursor plots or
time-series plots in the Stats1 plugin?
It appears that your medm build is not correct or your X server is not working correctly, that window should not be blank.

Actually you were right, SCIPLOT=YES was set in ~/epics/extensions/configure/os/CONFIG_SITE.linux-x86.linux-x86
but it was commented out in medm Makefile. Upon activation, all the plots can now be seen successfully.


>The Stats plugin also shows that you blew through all your buffers so you might be dropping frames somewhere.

Are you looking at "Dropped Arrays : 14429" to understand this phenomenon.
I have not changed any setting for obtaining these Stats.
Even after increasing buffer sizes to 8 MB, I still see many dropped frames but ImageJ shows frame rate of ~45 FPS while in MEDM it shows ~65 FPS.

Another problem is that, my ImageJ display only shows Grayscale images. When I change the image type from Common Plugin Window of CC1 and CC2 color mode property to either RGB1 or YUV444 or like wise, the IOC crashes showing

./start_epics: line 1:  4881 Segmentation fault      (core dumped) ../../bin/linux-x86/aravisGigEApp st.cmd

while MEDM gets disconnected showing the following error and the camera stays in acquisition mode unless I shut power down.

medmCAExceptionHandlerCb: Channel Access Exception:
  Channel Name: Unavailable
  Native Type: Unavailable

  Host: Unavailable

Please let me know if there is any other setting that I must do to make color images relayed without crashing IOC.

Thanks.

The Stats plugin also shows that you blew through all your buffers so you
might be dropping frames somewhere.

Hi Ashish,

NDPluginStdArrays does not have anything to do with the Stats1 plugin.  It
appears that your medm build is not correct or your X server is not working
correctly, that window should not be blank.  I have never seen that.

Can you open other plot windows in medm, e.g. the cursor plots or
time-series plots in the Stats1 plugin?

> Could you please suggest any other mode to obtain plots of pixel vs

ImageJ has a nice tool for displaying live profile plots.  Draw a line
across your image with the Line tool, and then select Analyze/Plot profile,
and then press the Live button to see a live profile that updates with each
new image.

Mark

Hi Mark,

I have understood your concern and have changed it to 20e6. Meanwhile I am
following your link to mitigate problem of dropped frames.
I have another question:
while in MEDM, as per attached screenshot in image4.png (All common plugins
enabled), NDPluginStdArrays is enabled, but still I don't get any
statistical plot in Stats1 window (image5.png - A blank histogram window can
be seen).

Moreover, after camera image display my aim is to obtain the x-y intensity
plot of ROI for which when I see
https://cars.uchicago.edu/software/epics/areaDetectorViewers.html
I, found that IDL may prove to be useful. But I could not download its
virtual machine setup for linux (ubuntu 16.04 here). Could you please
suggest any other mode to obtain plots of pixel vs intensity in x and y
axes.

Thanks.

Ashish

Hi Amish,

No, you should not set it to a number that large.  My understanding is that
Channel Access server and/or client will actually allocate arrays of size
EPICS_CA_MAX_ARRAY_BYTES, so you should set it just a bit larger than your
largest image.  That is explained in the documentation link I sent you.

Hi Mark,

Thanks again. Actually I also spotted all these mistakes and set
EPICS_CA_MAX_ARRAY_BYTES=2147483648. By doing so, I was able to start ImageJ
display.
I could also set NDPluginStdArrays enable from MEDM.
As per your suggestion, I shall now work on dropped frames.

Thank you very much once again.

I assume these are all of your EPICS environment variables?  If so, I see 2
problems.
1) You have misspelled EPICS_CA_AUTO_ADDR_LIST, you left out the T in AUTO.
2) You have not set EPICS_CA_MAX_ARRAY_BYTES.  Set that to 20000000 (20
million) to be safe with your cameras.  The NDStdArrays plugin will not work
without that being set.  It is documented here:
https://areadetector.github.io/master/ADViewers/ad_viewers.html<https://area
detector.github.io/master/ADViewers/ad_viewers.html#epics-ad-viewer-java>

Those are actually just warnings, and they won't stop things from working
correctly, so let's ignore those for now.

In order to prevent dropped frames you need to increase some Linux network
buffer settings.  I have documented how to do that here.
https://areadetector.github.io/master/ADGenICam/ADGenICam.html#linux-usb-and
-gige-system-settings

It can also be helpful to enable Jumbo Frames on your network card. You can
do that in your Linux network system settings.

I can see that you have collected many frames OK because the
ArrayCounter_RBV on your screen shot is 4816.

> Next, image1.png and image2.png you can also see ImageJ plugins being

Pressing Start in ImageJ only starts the ImageJ display, it does not control
the camera at all.  To start the camera you need to press Start on the medm
display.  Please send a screen shot of the main medm window after you press
Start there. What is the Image rate, i.e. frames/s?

You did not send the screen shot I asked for.  Please press the Plugins/All

> I have epicsV4 installed at ~/epics/epicv4/ but I don't know whether this

NDPluginStdArrays does not use epicsv4 at all, it only uses standard EPICS
Channel Access.

> I am also facing trouble with ADSpinnaker IOC as it does not start from

I am not sure what you mean by "template" in this context?  There is an
example IOC in ADSpinnaker.

Hi Ashish,



> Message: Identical process variable names on multiple servers


These errors a coming because you have more than one network card on your
machine, and you are running both the EPICS IOC and the EPICS client (medm)
on the same machine.  This is an annoying problem with EPICS, but it is easy
to fix.


You need to set these environment variables


EPICS_CA_AUTO_ADDR_LIST=NO

EPICS_CA_ADDR_LIST=xxx.xxx.xxx.xxx


where xxx.xxx.xxx.xxx is the broadcast address of the network you want to
use for EPICS Channel Access.  It is typically the public network interface
of your machine, rather than one of the private network interfaces.  On my
machine I might have private network address of 192.168.0.1 and a public
network address of 164.54.160.202.  I set EPICS_CA_ADDR_LIST=164.54.160.255
because the netmask of the public interface is 255.255.255.0.

You actually have 4 choices of drivers to use with that camera.

- aravisGigE.  This is based on the aravis package.  It runs on most any
version of Linux, and it should work fine.

- ADAravis.  This is also based on aravis, but uses the new ADGenICam base
class.  It also runs on most any version of Linux, and it should work.  It
queries camera properties more frequently than aravisGigE and so has
performance problems with some cameras because aravis does not currently
properly cache camera registers.  The aravis developer is working on this
problem.

- ADSpinnaker.  This uses the new Spinnaker SDK from FLIR.  It runs on
Windows and Linux.  The SDK is built with very recent version of gcc so they
only claim it works on Ubuntu 18.  In fact it may work on Ubuntu 16, and it
has been tested on RHEL8.

- ADPointGrey.  This uses the older FlyCap2 SDK from FLIR/Point Grey.  It
runs on Linux and Windows.  The version of the FlyCap2 SDK included in
ADPointGrey runs on RHEL7, although the more recent versions of the SDK
require Ubuntu (16 or 18?).

> Still I am unable to see the ImageJ display and NX, NY, NZ still being

Have you enabled callbacks on the plugins in question?  NDPluginStdArrays or
NDPluginPva for ImageJ, depending on which ImageJ plugin you are using.
NDPluginStats for the histogram plugin.  If you still have problems please
send a screen shot of those plugin screens.

First of all, you do not have the EPICS_DISPLAY_PATH variable set that
points to the location of the adl files in ADCore.

If you are using a FLIR camera, you should probably be using just the
GenICam and ADSpinnaker directories, not the Aravis ones.

The duplicate PV's are caused my most OS's these days having more than 1
ethercard, or virtual ethernet cards. You normally solve this by setting the
EPICS_CA_ADDR_LIST to a single ip # ( or even to 127.0.0.1) and setting
EPICS_AUTO_ADDR_LIST to NO

This is corresponding to my Camera ID.
then upon running ./start_epics it loads the db from template (~ 1202 PVs).

Next I installed the MEDM package successfully and ran

Upon Pressing "Acquire" button, the camera link LED is constant ON and I
think it starts acquiring as well.
After that I installed ImageJ and Java on my PC and subsequently added and
complied/run the EPICS_areaDetector Plugins (i.e. EPICS AD Controller, EPICS
AD Viewer, EPICS NTNDA Viewer).
When I started EPICS AD Viewer and added my PV prefix as 13ARV1:image1: (it
is shown in green highlight) and status is 4/9/2019 14:49:51.869: Connected
to EPICS PVs OK

But on pressing Start nothing happens, 4/9/2019 14:51:23.206: Image display
started message is displayed but no display is actually started and NX, NY,
NZ and Frames/s boxes are still empty.
However, the console of ImageJ shows the following issues:
