There is also an option in newtimef to define multiple baseline periods on continous data for computing significance between conditions.</div><div><br></div><div>Arno</div><div><br><div><div>On 14 avr. 09, at 19:10, Gethin wrote:</div><br class="Apple-interchange-newline"><blockquote type="cite"><span class="Apple-style-span" style="border-collapse: separate; color: rgb(0, 0, 0); font-family: Helvetica; font-size: 12px; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; orphans: 2; text-align: auto; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-border-horizontal-spacing: 0px; -webkit-border-vertical-spacing: 0px; -webkit-text-decorations-in-effect: none; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0; "><div lang="EN-US" link="blue" vlink="purple"><div class="Section1"><div style="margin-top: 0cm; margin-right: 0cm; margin-left: 0cm; margin-bottom: 0.0001pt; font-size: 12pt; font-family: 'Times New Roman'; "><font size="2" face="Arial"><span lang="EN-GB" style="font-size: 10pt; font-family: Arial; ">Dear all,<o:p></o:p></span></font></div><div style="margin-top: 0cm; margin-right: 0cm; margin-left: 0cm; margin-bottom: 0.0001pt; font-size: 12pt; font-family: 'Times New Roman'; "><font size="2" face="Arial"><span lang="EN-GB" style="font-size: 10pt; font-family: Arial; "><o:p> </o:p></span></font></div><div style="margin-top: 0cm; margin-right: 0cm; margin-left: 0cm; margin-bottom: 0.0001pt; font-size: 12pt; font-family: 'Times New Roman'; "><font size="2" face="Arial"><span lang="EN-GB" style="font-size: 10pt; font-family: Arial; ">We are using newtimef to run a time-frequency decomposition of our data. As we are interested in exploring low frequency (delta) activity, the function automatically removes the first and last 1.7 seconds of data. As an alternative to changing the parameters of the decomposition to include fewer cycles (or using very large overlapping epochs), we wanted to run the analysis on continuous data so that we only need to remove the first few cycles of each block. I can’t seem to run newtimef on continuous data (perhaps because it cannot calculate ITC?). One potential workaround would be to pull out blocks of data as epochs (say 100second epochs) and run newtimef on these “epochs”. This would still require some juggling to get the true trigger values back in but would at least mean running the decomposition on less overall data (although this seems to reintroduce memory issues). Given that I can use the complex data output to calculate the phase coherence myself can anyone suggest a simple workaround to avoid apparently needlessly analysing epochs that overlap with the previous 2 or 3 trials for every single trial?<o:p></o:p></span></font></div><div style="margin-top: 0cm; margin-right: 0cm; margin-left: 0cm; margin-bottom: 0.0001pt; font-size: 12pt; font-family: 'Times New Roman'; "><font size="2" face="Arial"><span lang="EN-GB" style="font-size: 10pt; font-family: Arial; "><o:p> </o:p></span></font></div><div style="margin-top: 0cm; margin-right: 0cm; margin-left: 0cm; margin-bottom: 0.0001pt; font-size: 12pt; font-family: 'Times New Roman'; "><font size="2" face="Arial"><span lang="EN-GB" style="font-size: 10pt; font-family: Arial; ">Many thanks in advance<o:p></o:p></span></font></div><div style="margin-top: 0cm; margin-right: 0cm; margin-left: 0cm; margin-bottom: 0.0001pt; font-size: 12pt; font-family: 'Times New Roman'; "><font size="2" face="Arial"><span lang="EN-GB" style="font-size: 10pt; font-family: Arial; "><o:p> </o:p></span></font></div><div style="margin-top: 0cm; margin-right: 0cm; margin-left: 0cm; margin-bottom: 0.0001pt; font-size: 12pt; font-family: 'Times New Roman'; "><font size="2" face="Arial"><span lang="EN-GB" style="font-size: 10pt; font-family: Arial; ">Gethin<o:p></o:p></span></font></div><span><ATT00001.txt></span></div></div></span></blockquote></div><br></div></body></html>
