Ran into the following errors when executing the command

bci_dat2stream < myfile | bci_stream2table --output=mynewfile

on some bci2000 files.

Code: Select all

subject4/EEG/subjectTM_4/TMsubject04S001R06.tsv
Runtime Error: Unhandled exception of type std::out_of_range: vector::_M_range_check
Aborting bci_stream2table

Also, is there any particular reason why bci_stream2table appends a hash (#) character to the header row and tab stops to the beginning of each line? This is kind of confusing.

For reference, here is the complete script that searches for .dat files in all subdirectories and converts them to tab-separated value files with the same name. Requires the fish shell and sponge.

Code: Select all

#!/usr/bin/fish

set filelist (ls **.dat)
# echo $filelist[1]


for infile in $filelist
	set outfile (basename $infile .dat)
	# echo $outfile".tsv"
	# echo (dirname $infile)"/$outfile".tsv
	set savefile (dirname $infile)"/$outfile".tsv
	echo $savefile
	bci_dat2stream < $infile | bci_stream2table --output=$savefile
	
	# Remove single hash character from file start
	# sed '1s/^.//' $savefile >> $savefile
	# better method
	tail -c +2 $savefile | sponge $savefile

	# remove first character from each line
	sed 's/^.//g' $savefile | sponge $savefile
end

I am having the same issue. I am running the following command

Code: Select all

$ bci_dat2stream.exe < testS001R01.dat | bci_stream2table.exe

and getting the following result

Code: Select all

Anyone have any suggestions?
