Compute several PSD at once

Hello,

quick question: I would like to compute several PSD at once (one for every recording).
Is it correct to place all the raw files in Process1 and then select Frequency > PSD ?
Would it compute all PSDs independently or would that mix them up on some way?

Thank you

François

Hi François,

Indeed you can load multiple files in process1 and the PSD's would be computed independently. This is also done in the first part of the tutorial on PSD analysis :

Kind regards,

Just make sure you select the option "Save individual PSD values (for each trial)".
