Errors in tuto2_FFT openvibe while reading EEGdata from .csv
Posted: Wed Mar 06, 2019 3:43 pm
Hi all,
I am using EEG Cap; g.tec Mobilab+; g.Saharabox to obtain EEG data.
First, I recorded EEG data into csv file.
The, I tried to play openvibe box tutorials tuto2_FFT_filter. Instead of Generic stream reader, I replaced it to CSV file reader and kept epoch time duration 2 and intervel as 0.5 sec. I specified the path properly both Matlab working directory and Matlab executable file. I want to add noise at 6Hz frequency and display the signals. 5 errors are occuring while performing this scenario. They are:
[ ERROR ] At time 0.000sec <Box algorithm::(0*00006669, 0*00003b2c) aka csv file reader> : {Error discription} : {Error in header file. Details: First Column (Time:8*257:256) is not well formed}, {Errorotype::internal (code2)}, {Error location} : {C:\ovm\sdk\plugins\processing\file-io\src\box-algorithms\csv\ovpCBoxAlgorithmOVCSVFileReader.cpp::81}
[ ERROR ] {Error description} : {Box algorithm <TCP Writer> initialization failed}, {Error type} : {ErrorType::Internal (code 2)}, {Error location} : {C:\ovm\sdk\kernel\src\kernel\player\ovkCSimulatedBox.cpp::105}
[ ERROR ] {Error description} : {Failed to initialize player}, {Error type} : {ErrorType::Internal (code 2)}, {Error location} : {C:\ovm\sdk\kernel\src\kernel\player\ovkCPlayer.cpp::212}
[ ERROR ] The player could not be initialized.
[ ERROR ] The initialization of player failed. Check the above log message to solve the issue.
I am not understanding what these are...Can anyone suggest how to avoid these errors?
