<div>Thanks Makoto for the web-links! I am a newbie in the EEG area. I located the webpage where I read Matlab<a></a> becomes unstable with single precision data. I am sorry I confused this with Matlab<a></a> 2014 when this issue was posted in 2008! Here is
the link: </div>

<div><font face="tahoma">Based on what was discussed on this weblink<a></a>, does the current EEGlab<a></a> by default store data as double precision when data is imported from EEGLab<a></a> in floating point format?

<div class="gmail_extra">Really? If you say some of EEGLAB/Matlab functions cannot handle single precision data since default is double, that makes sense.</div>
