<div dir="ltr">Hi Adam,<div><br></div><div>In this case you have three options:</div><div><br></div><div>1- time-lock to the beginning of the stimulus, baseline from -1000 to 0 and then shift your time axis of 2000ms (this requires the stimulus duration to be fixed)</div><div><br></div><div>2- use the complex numbers in tfdataStand, which are not baseline corrected, to extract the measure of choice (ersp/itc) and apply the baseline manually (this requires some minimal technical knowledge)</div><div><br></div><div>3- hire a grad student/postdoc who does the job for you (this requires the capacity of keeping a grad student/postdoc for longer than a few months)</div><div><br></div><div>Let me know if you need help with #1 or #2. Unfortunately, I can't help with #3.</div><div><br></div><div>Good luck,</div><div>Francesco</div><div><br></div><div><br></div><div><br></div><div id="m_2198125162050838318DAB4FAD8-2DD7-40BB-A1B8-4E2AA1F9FDF2"><br>
