Probe for EPMA / Re: Cisco AMP Antivirus and PFE
« Last post by Mike Matthews on January 18, 2019, 11:05:58 am »
We had an issue several years ago with an Oxford Instruments Inca dll being mistakenly picked up as a virus threat. Fortunately it didn’t stop the software working (although our IT security team did throw a hissy fit, demanding to know how we’d introduced a virus even though we’d told them about the known issue). I think we contacted the anti-virus vendor with the conflict and it was resolved with the next update.

Probe for EPMA / Re: Cisco AMP Antivirus and PFE
« Last post by Probeman on January 17, 2019, 09:02:29 pm »
Hi Paul,
It would be interesting to learn more about this. Please keep us informed on your investigations!   :)

At the Univ. of Oregon the university provides us with McAfee anti-virus. We have this running on all the computers in our lab, mostly Windows 7 and 10, including the Probe for EPMA/Thermo computer and the PeakSight computer, with no issues. So  far at least!

Our FEI Quanta runs on a computer which off the campus network, because the FEI software can't be updated and must be run on Windows 2000!  Apparently we have to buy a new instrument to get updated software!   :(

What experiences have others had with other anti-virus software packages?

Probe for EPMA / Cisco AMP Antivirus and PFE
« Last post by pvburger on January 17, 2019, 08:50:32 am »
Just wanted to let folks know that Cisco AMP for Endpoints may interfere with the proper functioning of Probe for EPMA. This is a virus scanner/network threat detection tool recently pushed by our organization. The symptom, when running PFE (on Windows 10 in our case), is a popup box titled "PositionGetSampleData" with a message reading "Could not lock file." Any PFE process running at the time the error is thrown is halted. A temporary workaround is to disable the Cisco AMP program.

To disable the program, you'll first want to disconnect from the network which provides your internet access. This is because shutting off your antivirus software will leave your machine vulnerable to viruses, malware, network attacks, etc. Next, to stop the Cisco AMP program on a Windows 10 machine, click on the Processes tab in Task Manager. Find Cisco AMP Tray Client, and click End Task. Also, find Cisco AMP for Endpoints Connector and do the same. This should take care of it. Remember to re-enable Cisco AMP once you're finished using PFE!

As I suggested, this is a temporary workaround, as you may want your machine to have internet access on a regular basis. Another possible workaround is to add exclusions to Cisco AMP for PFE. When I have time, I may experiment with this to see whether Cisco AMP and PFE can be made to peacefully coexist.

Cheers!

Dear colleagues,

Apologies for any cross-postings, but we would like to draw your attention to M&M 2019 Symposium P10: Applications of integrated electron probe microscopy and microanalysis techniques in characterizing natural and synthetic materials. The submission portal is open! Submit your 2-page paper as soon as possible at https://www.microscopy.org/MandM/2019/. The deadline for abstract submission is Friday, February 15.

Symposium Description: Electron microbeam techniques, such as SEM/ESEM, EPMA and TEM/STEM, use a focused electron probe or a small parallel electron beam to bombard a specimen and generate signals at a scale from micrometer down to Angstrom level. These signals include secondary electron (SE), backscattered electron (BSE), characteristic X-ray, cathodoluminescence (CL), transmitted electron, diffracted or scattered electron, etc. Information acquired using these signals includes image, chemistry and crystal structure of a specimen at micrometer, nanometer and sub-Angstrom levels.

We welcome contributions covering the entire range of electron probe microscopy and microanalysis of natural and synthetic materials, such as:
•          Imaging from SE, BSE, X-ray, CL, charge contrast, transmitted electron, diffracted or scattered electron, etc.
•          Qualitative and quantitative determination of chemistry of natural and synthetic materials
•          Repeatability, reproducibility and compatibility of quantitative microanalysis standards
•          Crystal structure determination using electron diffraction or electron backscattered diffraction (EBSD)

Feel free to share this information to other potentially interested colleagues. We are very much looking forward to seeing you in Portland!


Best Regards,

The organizers of Symposium P10:
Donggao Zhao, University of Missouri-Kansas City
Minghua Ren, University of Nevada - Las Vegas
Owen Neill, University of Michigan

Probe Image / Re: Post processing and data analysis
« Last post by John Donovan on January 14, 2019, 06:41:13 pm »
1. When you say "conversion of text images from ProbeImage" do you mean you are reading and converting the .PrbImg Probe Image files directly?

2. Does your code work for both Cameca and JEOL "flavors" of .PrbImg Probe Image files?
john

Nothing so fancy, I'm afraid, it simply imports the ascii text files as exported from CalcImage (not Probe Image, my mistake!) or the csv files as exported by the JEOL mapping software. These could be either raw intensity data or concentrations.

I use this script to replace some of the functionality of Surfer (e.g. making the pretty final images) as most users don't have this (yes, they could use the offline processing PC, but learning Surfer seems overkill for most of what people would use it for). You could then use imageJ to export line profiles etc - although a lot of this functionality is done by the new polygon extraction features!

Hi Jon,
OK, that makes sense now.  That will allow everyone to process quant x-ray maps from CalcImage in ImageJ, which is very nice.

Yes, Surfer is great for making fine adjustments for high quality presentations of x-ray map quant data, especially for publication, but it's not a cheap package, and really it's overkill for most basic operations of exporting selected pixel areas and/or min/max element filtering as you say. 

In fact I think we (and our students) should thank Gareth Seward again for working with us to implement the polygon extraction and pixel filtering feature in CalcImage.  It came out quite nice we think, and of course it is available to all students (and all their computers!):

CalcImage / Re: Polygon Extraction and/or Pixel Filtering
« Last post by John Donovan on January 14, 2019, 11:38:23 am »
Hi John,

Thanks you've got it, I was describing the need for standard error (I'd calculated the standard error without realizing it) when averaging pixels.

Your previous question 'long concentrations' should have read 'low concentrations' but it is a problem for all concentrations. I'll modify the post

Ben

Hi Ben,
OK, cool.

I can imagine that some might like to see the actual standard deviations and some might want to see the standard errors.

I'll see if we can squeeze in an additional option button or checkbox somewhere!   Won't be until this weekend though, sorry.

Following on from Ben's lead, I've been working on expanding the macro for automating the import and conversion of text images from ProbeImage in to ImageJ and out again as jpeg with scale and calibration bars.

Hi Jon,
Very cool.  Some questions: 

1. When you say "conversion of text images from ProbeImage" do you mean you are reading and converting the .PrbImg Probe Image files directly?

2. Does your code work for both Cameca and JEOL "flavors" of .PrbImg Probe Image files?
