Warning on DataIOfilter

Post by joanllo » 12 Nov 2015, 13:23

Hi guys,

We want to perform an SMR motor imagery neurofeedback training with our ANT Asalab amplifier and BCI2000. We downloaded the TMSIADC source tool to connect our ampli with BCI (following this topic: http://www.bci2000.org/phpbb/viewtopic. ... tmsi#p8175).
When we do a Stimulus Presentation application or a Cursor Task we obtain a logfile with a warning which repeats all the run. Eventually, the operator overflows and fall into a fatal error. What's going on?

We already tried to change the SampleBlockSize and Sampling Rate parameter (always into our computer processor capabilities) but the warning is always there.
