Hi Anne:
<div class=""><br class="">
</div>
<div class=""><span class="Apple-tab-span" style="white-space:pre"></span>Thank you so much for your thoughtful suggestion! I will give it a try.</div>
<div class=""><br class="">
</div>
<div class=""><span class="Apple-tab-span" style="white-space:pre"></span>Yes, we would like to have all the time continuous because we need to make some analysis based on the entire duration.</div>
<div class=""><br class="">
</div>
<div class=""><span class="Apple-tab-span" style="white-space:pre"></span>Happy Thanksgiving (if you are in the US)!</div>
<div class=""><br class="">

<div class="">cheers,</div>

Hi Mona,
<div class="">
<div class=""><br class="">
</div>
<div class="">if you do</div>
<div class="">cfg=[];</div>
<div class="">all=ft_appenddata(cfg, data1, data2, data3, data4); </div>
</div>
<div class=""><br class="">
</div>
<div class="">you get among the other fields</div>
<div class="">all=</div>
<div class="">time: <span class="Apple-tab-span" style="white-space:pre"></span>{1x4 cell} %assuming each dataset equals one trial, which is what you want to replace.</div>
<div class=""><br class="">
</div>
<div class="">you could try to create a matrix, based on your sampling rate with all the continuous time points, here just for illustration: </div>
<div class="">all_timepoints=[0:0.025:9.975] %<b class="">adapt to your sampling rate and length of data</b>, be very sure the end of one file is the beginning of the next one. (This is giving you all points from 0 to 9.975 with steps of 0.025)</div>
<div class="">trl_timepoints=mat2cell(all_timepoints, 1, [100 100 100 100]) %here I create 4 cell arrays, corresponding e.g. to 4 trials</div>
<div class=""><br class="">
</div>
<div class="">will result in</div>
<div class="">
<div class="">trl_timepoints = </div>
<div class=""> [1x100 double] [1x100 double] [1x100 double] [1x100 double] </div>
</div>
<div class=""><br class="">
</div>
<div class="">with continuous time information (trial 1 starts at 0, trial 2 at 2.5, trials 3 at 5, and trial 4 at 7.5) of the same length.</div>
<div class="">this you can then use to replace the original time information:</div>
<div class=""><br class="">
</div>
<div class="">all_data.time_old=all_data.time %if you want to keep the original time information</div>
<div class="">all_data.time=trl_timepoints</div>
<div class=""><br class="">
</div>
<div class=""><b class="">In general: </b>are you really sure that you need the continuous time information? There are many processing and analyses steps that can be done on the appended time information…</div>
<div class=""><br class="">
</div>
<div class="">There might be more elegant ways to do this.</div>
<div class=""><br class="">
</div>
<div class="">Hope there is no typo and that it helps</div>
<div class="">Best Anne</div>
