<p>Hi Robert,</p>
<p>Thank you so much for your reply!</p>
<p>In my preprocessing steps, I select the MEG electrodes only, so I
loose the trigger information (that is the STI101 channel). So it
is not due to downsample but to the fact that I suppressed the
channel myself (I still have the info for the triggers I have
selected during the preprocessing step -trialinfo-, BUT NOT for
the other following triggers that should appear in the
segments)... However, if I keep all channels, I wonder that since
the trigger channel send a pulse signal at 250Hz, if I downsample
below this value (e.g. 150Hz), will I loose the pulse signal? That
was my question. What do you think?</p>
<p>Best regards,</p>
<p>Carine<br>
