Hi Eleanor,
<div class=""><br class="">
</div>
<div class="">Could it be that you have an unexpected version of resampledata on your matlab path? What do you get if you type which resampledata on the matlab command line?</div>
<div class=""><br class="">
</div>
<div class="">Best wishes,</div>

Dear community,
<div class=""><br class="">
</div>
<div class="">I am new to fieldtrip and am trying to preprocess my EEG data so that it was be compatible with later analysis using cosmomvpa.</div>
<div class="">However, I keep running into the same error with the ft_resampledata function.</div>
<div class=""><br class="">
</div>
<div class="">When I attempt to downsample, this is the error I get</div>
<div class=""><br class="">
</div>
<div class="">Check for incorrect argument data type or missing argument in call to function 'resample'.</div>
<div class=""><br class="">

<div class="">Error in ft_resampledata (line 231)</div>
<div class=""> newdat = transpose(resample(transpose(olddat),fsres,fsorig));</div>

<div class="">data_eeg = ft_resampledata(cfg, data_eeg);</div>

</div>
<div class=""><br class="">
</div>
<div class="">I have checked previous posts to the community, to check that I am not encourting previously posted errors (I am downsampling from 1024Hz to 512, or have tried to 256, so this is a neat integer division which was a problem previously discussed
that produced this error with ft_resampledata).</div>
<div class="">I have ensured that I have specified all necessary configurations (cfg.resamplefs = 512; cfg.detrend = 'no';) and aside from this am using the default configurations.</div>
<div class="">When I remove the resampling section from my preprocessing pipeline script, it otherwise works fine, and works with mvpa functions from cosmomvpa.</div>
<div class="">I tried to apply the ft_resampledata function after the ft_preprocessing function as the help ft_resampledata notes indicate that data should be</div>
<div class="">resampled as obtained from the ft_preprocessing function, but encounter the same error even if I rearrange when I use ft_resampledata (before pre-proc, right after importing data).</div>
<div class=""><br class="">
</div>
<div class="">I also encounter this error when I try to run tutorial fieldtrip preprocessing scripts that I have downloaded from the cosmomvpa website - so the error isn't unique to my script.</div>
