[Eeglablist] pop_biosig woes

[Ramón Martinez]

Dear EEGLAB users,
Since December, a new BIOSIG version (v2.95) has been available from the
EEGLAB plug-in manager. If you have not yet done so, please update BIOSIG
using the EEGLAB plug-in manager. In case input/output issues still
persist, please, file a bug report on Bugzilla
<https://sccn.ucsd.edu/bugzilla/>.
Thanks,
Ramon
 (on behalf of the EEGLAB Team)
