Re: [Biosig-general] Opening CNSystems .fef files

[Alois S. <alo...@is...>]

Hi Rafal,


support for FEF is not implemented as m-file, but only as mex file.
Please ensure that mexSLOAD.mex* for your operating system is included 
in the matlab path.

Does this help ?

Best regards,

[Biosig-general] Opening CNSystems .fef files

[Rafal P. <rpa...@gm...>]

Hello :)
I working in NCUniversity Medical Department in Bydgoszcz, Poland. Trying
to do my PhD with heart rate signals.
Recently I am struggling with .fef extension files - I have original Task
Force Monitor software so I can open all my files, however, I cannot export
the data into matlab formats (which should is one of basic TFM functions -
I am getting an error) - seems like all this software is pretty old and
does not work well in Windows 11. I am trying to use your biosig tool and I
have just received this warning:

Warning SOPEN: Implementing Vital/FEF format not completed yet. Contact <
Bio...@li...> if you are interested in this feature.

So yes - I am interested in this feature :) Can you help me with extracting
the raw signals from my files?

Re: [Biosig-general] improving Biosig code base - List of ideas

[iuri iurix.c. <iu...@iu...>]

Hello Alois,
That’s interesting. Let’s get started then. I reviewed the initial documentation at http://biosig.sourceforge.net/IdeasList.html

How can I start? Where do I find further info regarding the first project biosigdump and biosigimport?

Furthermore, I’m going to prepare a box exclusively to BioSig projects. So, things first.
1. Can we work with Docker containers? Or we must install an entire VM ?  or a physical machine?
2. are we going to need a significant processing power for that?  (if so, can a Macbook pro 2.5Gz 16Gb ram do the job?
3. Are we going to need Matlab? or only C and C++ compilers?
4. What else aside BioSig itself must be installed ?

Best wishes,
Iuri

Dear Iuri,


thanks for your interest. Based on your skill set, I would order the suitable project in the following way:

1. biosigdump and biosigimport
2. Improving support for reading XML-based ECG data formats.
3. Fuzzing the biosig4c++/libbiosig code base
4. Bindings of libbiosig to new programming languages

For the other two projects it would be beneficial if you have already some experience with ECG or other biosignals. If your are interested in improving the Python-binding of biosig I do also see possibilities. For the item 2, somebody indicated already interest, but currently I can not estimate how serious that is, so if you are interested in that too, I'd suggest to coordinate, in order to prevent duplicating work.

Which topic(s) are you interested ? Or do you have other ideas, or interests for improving Biosig ? I know you package biosig for FreeBSD and Homebrew. Are you using Biosig already, and do you come across some topics that you would like to address ?

Biosig has between 500 and 1000 downloads per month (20-30 per day) for the last 15 years [1], it is packaged in a number of Unix/Linux distributions [2], and integrated and used by several other free software packages (e.g. eeglab, stimfit, sigviewer, ...).

Re: [Biosig-general] Converting .mat files to SCP ECG format

[Alois S. <alo...@is...>]

There is no readily available solution, in general there are a two 
possible approaches:

a) save to a gdf file  (see e.g. demo/demo3.m ), and then convert with 
the commandline tool to "save2gdf"  to scp
      save2gdf -f=SCP file.gdf file.scp

b) try to use mexSSAVE
      % fill in all other required fields in HDR according to 
biosig4matlab/doc/header.txt
      HDR.TYPE='SCP'
      HDR.FileName='test.scp'
      HDR=mexSSAVE(HDR,[]);

Writing of the mandatory sections of SCP should already supported, for 
optional sections support might be currently incomplete. We'd need to 
check how to implement that.


Cheers,
   Alois

[Alois S. <alo...@is...>]

Dear users of Biosig,


Biosig 2.4.1 has been released and is available for download from
http://biosig.sourceforge.net/download.html

The highlights are :
* improved usability and performance of the MOD method.
* sviewer - a predecessor of SigViewer running in Matlab - has
    been updated and can now read data through mexSLOAD.
* bug fix when reading IBW data (reported sample rate is now correct).

[Biosig-general] "Biosig for Python" is now available on windows through Cygwin

[Alois S. <alo...@is...>]

Dear users of Biosig,


Biosig is now also available through Cygwin [1,2]. This fills an 
important gap for running "Biosig for Python" on Windows [3]. Running 
"Biosig for Python" has already been possible for users of *nix 
operating sytems (including GNU/Linux, MacOSX and other *nix). Now this 
is also available to users of the Windows OS.

More information about Cygwin is available at [4]. Most likely when 
using Biosig in Python, you will might want displaying some data with 
matplotlib. In order to do so, you will need also Cygwin/X [5]. A 
screenshot about loading and displaying some demo data, running 
Python3.9.exe on a mate terminal under Cygwin/X is shown at [6].


Best regards.
    Alois

[Biosig-general] biosig 2.3.1 released

[Alois S. <alo...@is...>]

Biosig v2.3.1 has been released and is available from
     http://biosig.sourceforge.net/download.html

The main improvements are that support for a number of data formats is 
improved.
Specifically the following changes are included:

    EDF+ : relax requirement that reserved field must start with "EDF+"
    ABF2 : scaling of y-axis
    ATF : support multi-channel traces, segments will be concatenated
    (and not considered different channels)
    AXG : extend support to some real-world data sets



Cheers,

[Biosig-general] biosig 2.3.0 released / request for example data

[Alois S. <alo...@is...>]

Dear friends of the Biosig project,


Biosig v2.3.0 is released and available from here:
   http://biosig.sourceforge.net/download.html
The changes are listed below.

Most notable, basic support for files in ABF2 format as added.
In order to improve compatibility and testing its correctness,
I'm still looking for more test data, in various versions.

If you can provide more example data for testing, please upload them to
https://seafile.ist.ac.at/u/d/6dc9a1a7ce9f43b0acde/https://seafile.ist.ac.at/u/d/6dc9a1a7ce9f43b0acde/   https://seafile.ist.ac.at/u/d/6dc9a1a7ce9f43b0acde/
within the next 20 days. Uploads should also include
- example files in ABF2 format
- a short description,
- your contact address in case I've further questions
- ideally, also the data converted into some "known" format (e.g. ASCII, CSV, EDF, GDF, etc.)

If you have example data in any other data format, and would like to see better support in Biosig,
you can upload them as well. Just add also information about the dataformat, and which device/model was used to record this data.



Enjoy,
    Alois



- <NEW> basic support for reading ABF2 files added
- <NEW> rotary-decoder added (used in Zhang et al. 2020)
   biosig4matlab/t250_ArtifactPreProcessingQualityControl/rotary_decoder.m
- demo script of the MOD method (Zhang et al. 2021) improved.
- several bug fixes and minor improvements
- improvements in language bindings for Octave, Python and R

[Biosig-general] biosig 2.2.1 released

[Alois S. <alo...@is...>]

Biosig 2.2.1 is available. It is a bug-fix release that addresses mainly 
two issues:

- fix JSON export when sampling rate is undefined (e.g. Infinity)
- add sanity checks for certain input files, that could crash save2gdf

It is is strongly recommended to upgrade.

Biosig is available from
  http://biosig.sourceforge.net/download.html


Kind regards,

[Alois S. <alo...@is...>]

Biosig 2.2.0 is available
from here http://biosig.sourceforge.net/download.html

The main changes are

* biosig4matlab
- add Machine-Learning-Optimal-Detection (MOD) method (Zhang et al. 2020,2021)
   This method shows a significant improvement in detection performance over
   other known alternatives.
- fix issue eeglab#93 (encoding of EDF+ annotations)
- sopen (gdf): add support for timezone information
- fix install script for biosig4matlab


Enjoy and have fun,

[Biosig-general] biosig 2.1.1 released

[Alois S. <alo...@is...>]

Dear users of Biosig Software tools,


Happy New Year 2021. I hope you are doing well and COVID is not 
affecting you too much.
Maybe you are even working to tackle COVID (if Biosig is useful for this 
work, I'd be
certainly interested in learning about this - please let me know).

Biosig v2.1.1 release is now available and can be downloaded as always from
   https://biosig.sourceforge.io/download.html

The main new features are:
*) Support for Python and R on Windows:
   a mechanism for loading Biosig data into Python and R
   on the MS Windows platform. It consists of two parts:
   biosig2gdf.exe and loadgdf.{py,r}. biosig2gdf is an
   executable file that loads biosig data and converts
   it into a GDF data stream, this GDF data
   stream is then parsed by loadgdf.{py,r}. The data samples
   and some header information is returned.

*) biosig_vhdr_generator.sh ...
   ... is a tool to generate vhdr-header files for headerless
   binary *.dat files from a template header file.
   The header information is provided through a
   vhdr template file. This can be useful for data sets recorded
   with ktan and other recording systems. These header files
   can then be used to open the *.dat files with SigViewer
   and other Biosig tools without any data conversion.

*) some minor bug fixes.

Enjoy the new features of Biosig, stay healthy and all the best for 2021,

     Alois

[Biosig-general] biosig 2.0.4 binary releases for windows, and biosig4octmat v3.7.0 available

[Alois S. <alo...@is...>]

After almost a month after the source release of biosig 2.0.4, now also
the binary release for windows finally available. The delay was caused
by the need to reorganize the directory structure in the released files.
Now, all parts (former biosig4octmat and biosig4c++) are now combined in
a single package Biosig-2.0.4.

For those who have been using "biosig4octmat", one last release
(v.3.7.0) is published. However, I recommend to use Biosig-2.0.4. Former
biosig4octmat can now be found under $PREFIX/biosig/share/matlab . In
order to activate biosig4octmat, start Matlab or Octave, and run

   cd <PREFIX>/biosig/share/matlab

   install

   savepath 


There is also a significant change in the Mathematica binding: 
sload.exe module has been renamed to "biosig.exe", and provides Sload
and Uload. You can find it in $PREFIX/biosig/mathematica. The example
usage are shown in $PREFIX/biosig/share/mathematica


If you work on *nix systems, it is recommended to compile from source as
show below. If you have Matlab, or Mathematica installed, the language
bindings will be installed automatically, and will become available by
default under

   /usr/local/share/biosig/matlab

   /usr/local/share/biosig/mathematica


* On *nix (GNU/Linux, MacOSX), its recommended to compile from source

   ./configure && make && sudo make install


* MacOSX: you can install Biosig also through Homebrew


   brew install biosig


If you see any bugs, or unexpected behaviour, do not hesitate to contact
me.


Best regards,

   Alois
