The following settings can be adjusted for PALbatch:

validation algorithm
Adjustable criteria for the validation algorithm
Wear time protocol:
- 24 hour wear – allows 4 hours of non-wear per day
- 14 hour waking wear day – allow 10 hours of non-wear per day
- 10 hour wear day – allow 14 hours of non-wear per day
classification algorithm
The classification algorithm can be selected and parameters adjusted.
VANE
The standard PAL analysis algorithm. Classifies the data into 3 event types – non-upright, upright and stepping.
Adjustable parameters:
- minimum non-upright period – for free living data in adult populations, the default value of 10 seconds is recommended
- minimum upright period – for free living data in adult populations, the default value of 10 seconds is recommended
CREA
Extends the standard PAL analysis algorithm to provide detection of non-wear and classification of non-upright time into lying (primary and secondary) and sitting. Seated transport and cycling classification are applied. Upright correction for intermediate sitting angles is also applied.
Adjustable parameters:
- minimum non-upright period – for free living data in adult populations, the default value of 10 seconds is recommended
- minimum upright period – for free living data in adult populations, the default value of 10 seconds is recommended
wear correction
With ‘Auto-correct inverted wear’ selected, data files where the device was worn upside down will be automatically corrected.
valid day filter
Options for using the valid day flag as generated by the validation algorithm
- Show all days – the valid day flag is not used
- Highlight valid days – valid and invalid days are marked
- Show only valid days – invalid days are trimmed from the start and end of the data
