Dear GGIR users,
I am using GGIR for the first time. With a few very minor tweaks the R script is working well with my Geneactiv watch data (although I have a concern with the calculations of IV and IS, but I'll raise that in a different thread).
The R script is not producing any output for Part 4. Output for Parts 1-3 and Part 5 are OK. The data quality report suggests that the data is OK. I feel there is something quite basic that I am missing. Any suggestions for a novice user?
I am not using manual sleep logs at this stage, but my understanding is that the GGIR package will estimate onset and offset times based on the data. Is that correct?
Thank you in advance
Ben Bullock
