Error when streaming data using run_readlsl plugin

[gleslie]

Step 1: Run SendData-mac or SendData64 on Windows to send fake BioSemi EEG stream
Step 2: run BCILAB-root/bcilab.m
Step 3: run_readlsl('BioSemi'); OR GUI/Online Analysis/Read Input From.../Lab Streaming Layer/ (default settings)

This Error is printed with each incoming sample:

Error in block-reading function:
Too many input arguments.

I'm having the same error, with slightly different line numbers, apparently: Too many input arguments.
occurred in:
run_readlsl/read_data: 182
@()read_data(inlet,marker_inlet,opts.always_double): 174
append_data: 61
onl_read_background/@(timer_handle,varargin)append_data(stream_name,stream_id,timer_handle,block_reader): 0
timercb: 31
timercb: 14

I'm not sure yet if the data is actually being read in despite the error, or not, although Lab Recorder claims it is taking in data, according to the updated tracker in the bottom left-hand corner that also tracks the time of recording.

Christian, do you know if this is a critical issue or an ignore-able one?

I am having the exact same error saying:
Error in block-reading function:
Too many input arguments.
occurred in:
run_readlsl/read_data: 183
@()read_data(inlet,marker_inlet,opts.always_double): 175

Did anyone of you managed to solve this?

After some debugging, I have found the error and sorted:
the problem was actually in line 182 of run_readlsl here:
data_clock = data_inlet.time_correction([],opts.clock_alignment,opts.clock_est_window);
here, in the code, 3 arguments are passed and that is why we get too many input arguments. Presumably the lsl_inlet class has been updated at some point and this function now only requires a single argument. You can read more about it in the respective documentation, but basically removing all inputs and passing in nothing will work just fine!

@HEPlab the data is definitely not getting read in, into Matlab with the error. Of course, it is recorded by labrecorder, but you won't have access to that data in real time in matlab workspace..
