<div>Hi everyone,<br>
<br>
<span style="font-family:arial,helvetica,sans-serif">I am now trying to use the DICS method for sourceanalysis, with 'powandcsd' output from ft_freqanalysis as its input and using a precomputed filter and leadfield. However, I would like to keep my separate
trial estimates in the final source analysis, and while the documentation suggests I should be able to get that with cfg.keeptrials, but this doesn't have the expected effect.<br>
<br>
</span></div>
<span style="font-family:arial,helvetica,sans-serif">I previously made workaround using PCC on fourier data instead (see below), I think to deal with this issue. I was wondering if this is still the recommended option, i.e. workaround? Alternatively, and perhaps
preferably, would someone have a suggestion for a solution consistent with the DICS implementation?</span><br>
<br>

Thanks for your time,<br>
