Frame slicing recordings and relative time vectors #2612
-
Hi all, Apologies if this information is currently available here or elsewhere, I was unable to find it. I am 'frame slicing' my original recordings to remove the initial portion. Then using these clipped segment recordings for further sorting and analysis. My question is do these clipped recordings have time vector information relative to the original recording? Or will I need to compute the sample offset manually? I have a second analog file from the same session that records relevant TTLs to align electrophysiology signals too and these are not clipped. Thank you for any insight or guidance on this question! Ben |

Hi Benjamin If you are frame slicing, then you get a new recording, with no memory from the original one. This is a slice or a view of your recording, and thus you'll have to manually adjust the times of the sortings. One other option would be to "silence" the beginning of your recording if you want to discard some data while keeping the times (see silence_periods in preprocessing filters) |

@yger actually timestamps are propagated if you slice a recording. Here's an example:
