I heard rumours that the source code of Easyspin will be published soon. Is this true? If so, at which time is this planned?
Thanks for your help
Charles

There is no explicit time frame for this. We anticipate 2017.

Are there any updates on this? I'm trying to develop a Python script to mimic eprload to use on a Raspberry Pi, but have had trouble decoding the .SPC files.

As I know, SPC file is a simple sequence or 4-byte floating point values. All other data are in the PAR file which is ASCII text.

The PAR/SPC format changed quite a bit over time, depending whether you look at ESP data, WinEPR data, etc.
Here are a few snippets that should help. Little vs. big endian can make a difference:
Code: Select all
% For DOS ByteOrder is ieee-le, in all other cases ieee-be
if isfield(Parameters,'DOS')
Endian = 'ieee-le';
FileType = 'w';
else
Endian = 'ieee-be';
end
The data could be complex or 2D:
Code: Select all
% Analyse data type flags stored in JSS.
if isfield(Parameters,'JSS')
Flags = sscanf(Parameters.JSS,'%f');
isComplex = bitget(Flags,5);
TwoD = bitget(Flags,13);
end
The file type determines the number type in SPC:
Code: Select all
% FileType: flag for specific file format
% w Windows machines, WinEPR
% c ESP machines, cw EPR data
% p ESP machines, pulse EPR data
% Set number format
switch FileType
case 'c', NumberFormat = 'int32';
case 'w', NumberFormat = 'float'; % WinEPR/Simfonia: single float
case 'p', NumberFormat = 'int32'; % old: 'float'
end

Are there any new plans to make the source code of Easyspin available as open source software?
Is it planed to port Easyspin to freely available frameworks like Python/Numpy ?

We are working on making the EasySpin source code openly accessible.
Regarding Python/Numpy, there are currently no plans. It would a significant effort, and we unfortunately don't have the bandwidth to do that.
