Louis,

I had a look at the file.
Which SVN revision of BCI2000 are you working with?

Regards,

Louis,

if your BCI2000 file was written by the BCI2000 framework, and cannot be read by a current version of BCI2000FileInfo, then this indicates a bug that needs fixing.

Thus, I would be glad to have the file that triggered the problem. Could you send it to my e-mail address?

Thanks,
Juergen

Kamyar, you don't need to re-run your experiments to try a different montage. Re-referencing in software will suffice -- unless there is a physical problem with your recording. To avoid physical extinction of signals by amplifier saturation, make sure that all your electrodes are the same material, ...

Louis, when terming your data acquisition module "home made", does this refer to a BCI2000 source module supplied with your own data acquisition class inheriting from GenericADC? Specifically, is the BCI2000 dat file written by the standard code shared by all existing source modules, or by...

Harsimrat, use the load_bcidat mex file available in tools/mex. Alternatively, you might consider recording into GDF format, and then to use BIOSIG to read in your data. More info about using GDF as an output format for BCI2000 is available at http://www.bci2000.org/wiki/index.php/Data_File_Formats ...

Louis, if the Mario error messages make any sense it appears that your acquisition module reports 12579 channels. That would be quite a few ;-) What does BCI2000FileInfo say when you use it to display your file's data format? Rather than BCI2000toASCII, try the load_bcidat mex file from tools/mex. S...

Louis,

you are welcome to submit your source module.
In the future, we plan to have a contribution area on the server. For now, I ask you to send your code to Gerv once it is finished, along with some documentation that allows others to use it.

Cheers,
Juergen

Louis, the error message from the DataIOFilter suggests that there is a problem with your ADC filter's instantiation -- the DataIOFilter cannot find an ADC filter instance to use for data input. There are some possible reasons for this -- - Is your ADC filter's cpp listed as part of your source modu...

Louis, currently, all BCI2000 modules are full Borland VCL applications rather than console applications. Borland project files are editable by hand but it is difficult to spot errors, so I recommend that you use the RandomNumber source module's project file as a starting point: 1) Create a new, emp...

Right now I store the data in parts to a file when the program is running instead of putting it all in memory and save by program termination. The header gets saved during program initialization and the the data gets saved every program cycle. This means that a file handle goes through the program ...

Though you say my parameters in my header does seem to follow the syntax it can indeed be read by load_bcidat.dll correctly as long as I put some binary data after it that has been recorded by BCI2000 and not my own system. In a BCI2000 data file, lines should be terminated the Windows way, i.e. wi...

Asbjørn, your FileInitials parameter contains space characters in its value. According to the parameter format as defined in the project outline, these characters should be encoded as "%20" (remove the quotes). In a parameter line, white space separates individual values, thus your FileIni...

Dear Febo,

going over the RDAClient code again, I found an inappropriate timeout value when waiting for the first block of data after establishing a connection.
This may well have been the cause of your problem, and can explain why it was so difficult to reproduce.

Best regards,

Binary distribution

Dear Phrozen, thank you for asking this question. We are currently restructuring the information on our website, and the link to the binary distribution got lost on the way, sorry for this. In the documentation wiki, there is now a page dealing with binary distributions: http://www.bci2000.org/wiki/...
