Re: error: eprload with matlab 2021b

Hi, I experience the same problem with 2021b. However, after investigating the eprload function, I think the problem lies in the base64 decoding of the data and not in interp1. The base64 decoding of the curves and subsequent typecasting to double returns just a scalar (line 96-98 in eprload_Magnett...

Re: Magnettech MS5000 transient measurements - wrong x-axis

It works like a charm now.

Thanks a lot!

Re: Magnettech MS5000 transient measurements - wrong x-axis

I tested the new version. The loading of the transient spectra works fine now. Thanks for that! However, now ES cannot load 2D measurements, such as saturation measurements, anymore. The error is Error using eprload Cannot construct abscissa for this measurement type There are no real 2D measurement...

Re: Magnettech MS5000 transient measurements - wrong x-axis

Apparently, the y data at t=0 s is just a copy of the value at t=0.022 s. Please see the attached screenshots.

Re: Magnettech MS5000 transient measurements - wrong x-axis

I found another small bug in the eprload() regarding the x-axis. The last about 70 values of the field axis are at least in the example of LOGSTest_001.xml from the first post are NaN (I also checked other files. All show the same behaviour). The reason for that is that the x-axis of the magnetic fi...

Re: Magnettech MS5000 transient measurements - wrong x-axis

Attached is the spectrum of LOGSTest_006 as shown in ESRStudio (MS5000 software). The time axis is from 0 to almost 10. However, I just saw the following. If the file is loaded with eprload I think the time is in Params.Curves.MW_Absorption.x and the EPR signal in Params.Curves.MW_Absorption.data. A...

Magnettech MS5000 transient measurements - wrong x-axis

Hello, eprload returns an incorrect x-axis for transient measurements at fixed B0 for the Magnettech MS5000 spectrometer. The x-axis is the magnetic field instead of time. The identifier for this type of transient measurement is in the xml file: Type="kinetic" as shown below <Recipe Name=&...

Magnettech dual-phase data

Hi all, the magnettech MS-5000 spectrometer has a dual-phase lock-in amplifier, the data of which stored in the xml files (identifier: MWAbsorption sinus and MWAbsorption cosinus) in addition to the standard output MWAbsorption. In the current version of ES only the standard output is read. However,...
