#13 Support for AES, EZ3, and ARC fiile formats

Alois Schloegl — Thu, 30 Sep 2021 04:51:39 -0000

The files biosig4c++/t210/sopen_cadwell.c and biosig4c++/t210/sopen_sqlite.c are used to develop tools for reverse enginering, and understanding and implementing support for these data formats. The extracted information can be displayed with save2gdf and a verbose level of 8 or 9.

Support for AES, EZ3, and ARC fiile formats

Alois Schloegl — Fri, 27 Aug 2021 19:36:52 -0000

AES, EZ3 and ARC are proprietary EEG data formats. EEG data is stored in this format by products of Cadwell. Unfortunately, Cadwell does not provide the specification for this data format.

#12 Support for MIT Physiobank 212, 310, 311 data format

Alois Schloegl — Sun, 28 Jun 2020 05:07:55 -0000

The bug is fixed in recent versions of biosig. When selecting the MIT-BIH files, the .hea file need to be selected.

#9 PhysDim becomes a function

-
 The field PhysDim in the struct HDR.CHANNEL\[k\] will become obsolete. PhysDim stores the physical units of the measurements, in future the physical units will be encoded in HDR.CHANNEL\[k\].PhysDimCode. 

 You can use the function PhysDim\(\) for converting PhysDimCode into a text string.

#9 PhysDim becomes a function

PhysDim3() is a more efficient implementation, doing all memory management internally. Applications do need to alloc/free memory for storing the sting.

SigViewer trunk crashes reproducible in libbiosig trunk sopen\(\) opening MIT-BIH hea files. Reproduction: 1\. Make debug build of libbiosig.so and SigViewer using the attached patches \(and possibly more manual override tricks I forgot to document since QT4 debug config support seems broken in debian squeeze, or broken qmake project config \*.pro\) 2\. Compile+Link SigViever NOT against ./extern but against the /usr installed trunk debug libbiosig.so and headers 3\. Launch SigViewer and open a MIT-BIH hea file from the File->Open GUI-dialog, should segfault in libbiosig->sopen\(\), see attached gdb output.

upgrade to numpy

brice — Wed, 21 Jul 2010 06:43:52 -0000

I am interested in the python port. I modified a bit the Makefile so as to add the correct include directories and I managed to generate biosig.py for python2.6 and numpy. I then ran the test. Although there was no execution error, the results do not seem to be correct \(for instance the last line says: "status channel, peak to peak amplitude of sin at 3.000000 Hz: 94.465793 \(should be 0.000000\)"\).

SigViewer: user-specified event description

Alois Schloegl — Fri, 13 Jun 2008 06:13:08 -0000

The meaning of event codes is pre-defined in the table of event codes. However, the table of event codes allows for user-specific annotations for codes 1 to 255. Now, HDR.EVENT.CodeDesc can return a list of these user-specific event codes \(e.g. for Brainvision and EDF+ data formats\). The length of the list is stored in HDR.EVENT.LenCodeDesc. Therefore, the description of the first HDR.EVENT.LenCodeDesc events should be defined by HDR.EVENT.CodeDesc. This would enable user-specified event descriptions.
