<div dir="ltr">Dear Lorna,<div><br></div><div>Wavelet transform at the STUDY level is performed by newtimef(), so it basically accepts optional inputs for newtimef(). If you want to specify the window size, there are two ways.</div>
<div>1. Use option 'winsize'; note it conflicts with other options so check out which overwrites which.</div><div>2. Compute it in this way: your lowest frequency x number of cycles. For example, if 'freqs', [3 128], 'cycle', [3 0.8], then 3 Hz = 333 ms per cycle and there will be 3 cycles at 3 Hz, which means your window size is approximately 333 ms x 3 cycles = 999 ms. If 'freqs', [2 128], 'cycle', [3 0.8], your window size will be 1500 ms; if 'freqs', [4 128], 'cycle', [3 0.8], it will be 750 ms.</div>
