I am looking for some help from someone to write a program in preferably python to sort two sets of time based data into order. There are (at least) two complicating factors. The first is the date and time statement is likely to be different between the two sets of data (c.f. 22/08/2019 09:32:23 and 22/08/19 9:33 and no doubt other variants). The second is the data is usually in txt or csv format but has different column divider codes (c.f. tab, comma, space etc.). One data set also contains the occasional null value for CO2 plus a host of program progress lines which need ignoring.
The purpose of the program is to take two sets of in cave CO2 and other data (pressure, temperature and relative humidity) obtained at different time intervals over a common time period and extract the CO2 reading from the more frequent data set timed closest to the time of each sample in the less frequent data set. I then want to do some statistical checking of how well the two sets of CO2 reading correlate. That might get complicated as a trail stab at it has indicated there could be a time lag between the two data sets.
If you are interested in helping develop a CO2 logger for use in cave, then please PM me.
many thanks in anticipation
