I noticed, that by mistake I removed ICA projectors before applying band-pass filter to data. What I did, was that I used 0.5Hz - 100Hz frequency band for display filters, ICA calculations (continuous data) and finally for the band-pass filtering of the data. In band-pass filtering I selected the option "Process the entire file at once".
I know that doing like this is something that you do not recommend. In tutorial: https://neuroimage.usc.edu/brainstorm/Tutorials/ArtifactsFilter#Apply_a_notch_filter
"When to apply these filters?
*Before SSP/ICA cleaning: Artifact cleaning with SSP/ICA projectors require all the channels of data to be loaded in memory at the same time. Applying a frequency filter on a file that contains projectors requires all the file to be loaded and processed at once, which may cause memory issues. Pre-processing filters are rarely changed, whereas you may want to redo the SSP/ICA cleaning multiple times. Therefore it is more convenient to apply the filters first."
I understood, that I could have had problems with computer memory, but that my data should still be valid. Is this true?
As usually, I noticed my mistake after I had all the results ready. So if you happen to know the answer, I would really appreciate your help.
Thank you in advance!
