Dayfile.txt: Difference between revisions

The Cumulus 1 editor provides a "Create Missing" option where it will, for any dates for which a line does not exist, create a line if it can from reading the [[Monthly log files|detailed log file]] to extract all values relevant to that day and do the necessary minimum/maximum/total/average calculation for each dayfile.txt field, storing the time from the relevant other log file in any time-stamp field in dayfile.txt. If a particular day does not exist as a row on the daily summary log, then 'create missing' can search the observations in the relevant monthly log, and calculate approximate highs, lows and totals to insert as an extra row in the daily summary log. These are approximate because the actual highs and lows for that day are quite likely to have occurred at moments in-between those that were logged. For ''Create missing'' a list of inserted records is produced in [[dayfileeditlog.txt]]. If just some fields are wrong in a particular row (meteorological day) on day file, then there is a [[Monthly_log_filesStandard_log_files#Using_Monthly_logs_to_deal_with_shorter_Using_Standard_logs_to_deal_with_shorter_.28or_incomplete.29_dayfile.txt_records_for_particular_dates | work around]] as at all current versions (up to 1.9.4) you can only use 'Create missing' to read from the [[Standard_log_files]] if the whole day (a line starting with that date) is missing in ''dayfile.txt''. Although Cumulus does not recognise the concept of a sensor not being available, it will write solar information even if you don't have a solar sensor; it does have to cope with reading a monthly log file that might have fewer derivatives than it wants (when using Create Missing) and therefore it may not know what to write into dayfile.txt as the calculated value. Cumulus 1 can't write a null value, so it writes zero for values, and "00:00" for time stamps. If you are using a 9am or 10am rollover time, be aware that create missing in Cumulus 1 always inserts 00:00 for null time-stamps, but in normal running Cumulus uses the rollover time for null time-stamps.

As an alternative to manual line ''insert'', in the Cumulus 1 editor, you may wish to use a procedure for importing, and processing, pre-Cumulus observations into [[Monthly_log_filesStandard_log_files]]. Once there is data for required days in monthly logs, ''Create missing'' can insert the new rows for those days previously missing in dayfile.txt.

{{Version badge 1}}Apart from bulk changes, Cumulus 1 made editing this log file quite easy. Although the create missing did not work where a line was present for the date, but an individual field needed to be corrected or populated, there was a [[Monthly_log_filesStandard_log_files#Using_Monthly_logs_to_deal_with_shorter_Using_Standard_logs_to_deal_with_shorter_.28or_incomplete.29_dayfile.txt_records_for_particular_dates |work around]] for this.

Ideally, you will subsequently try to edit the rogue data for the particular time it was logged; see [[Monthly_log_filesStandard_log_files#Correcting_any_logged_data_problems]], but correcting the daily summary in dayfile.txt must always be the priority.
