in my old lab we used a synamps2 system and never had problems importing the 68 channel cnt files, apart from some memory issues. This was between 2006 and 2008, so we probably used an older version of neuroscan ...<br>

I do not have an answer, but for what it's worth I have also never been able to import 32-bit .CNT files into EEGLAB (at least, not when running 32-bit Windows XP). On the other hand, I never had problems importing epoched .EEG files; therefore, my processing
pipeline involves first re-referencing and epoching the data in Neuroscan (if necessary, re-referencing could be done later in EEGLAB instead) and then importing the epoched data to EEGLAB for the rest of the preprocessing.<br>
<br>
I would also be very interested to hear about any solutions for importing the continuous data, though.<br>

Hello,<br>
<br>
I'm wondering if anyone else seems to have issues importing 32 bit neuroscan CNT files into eeglab (I've made sure that the 32 bit option is flagged when i go to read in the files). The data were recorded with a synamp2 64 channel amp. When I view the data
with the eeglab plotter data from several channels do not appear at any scale, and the latencies of the channels that do display seem off in comparison to what things look like in neuroscan 4.5. There was a similar post made around 2009 but no apparent resolution.
When I open epoched neuroscan EEG files, however, things seem fine. I suppose I could do all my preprocessing in neuroscan and then read in my EEG files, but I'm trying to move my entire pipeline into eeglab. Any help or even guesses would be wonderful.
<br>
<br>
Thanks,<br>
