Processing Derived Count Data For Sleep

[ppagan95]

I have actigraphy count data in a format similar to the Actigraph13.csv file linked as an example in the documentation, with variables for zero-crossing counts, total energy, and time above threshold, in 60s epochs, using 50 mg thresholds for energy and zero-crossing.

According to the cookbook and the documentation, externally derived data can be used with GGIR. Could you provide guidance on the feasibility of using GGIR to analyze these data?

Your question is not clear. Feasibility can mean a lot of things. Please make it more specific.

Would I be able to run part 4 of GGIR on my zero-count data to get sleep metrics if the file format does not match one-to-one to your supported formats, but it is in the .csv format?

If your file format matches one of the file formats that GGIR facilitates and if the count values are calculated identically to how it was intended by the original publication that described the sleep detection algorithm (Sadeh, Cole-Kripke, etc) then yes.
