Contains functions for processing and analyzing picarro respiration data from Lehmann lab parallel incubation rig
Installation instructions in R:
- library(devtools)
- install_github('domwoolf/picarro')
Required inputs:
data_path = directory containing all raw data from picarro analyzer within nested subdirectories. If data_path is not provided in the function call, it can be selected interactively. NB picarro files are assumed to end in .dat -- No other files in the data path should have this ending.
In addition to raw Picarro data, the data_path must also contain the following 2 files:
- fractional_volume.txt = provides fraction of head space gas divided by total volume including residal gas in the analyzer and pipework
- logfile (filename must start with the characters "logfile"), which contains epoch time, sample ID, and step ID: Step 2 = sample analysis, Step 3 = end of step 2, Step 5 = purge analysis, Step 6 = end of step 5
