== Create Missing ==
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_files#Using_Monthly_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.▼
If a date is missing from dayfile.txt, and not available in a back-up, then it is possible to create a missing line (with approximations for the derived extreme values) in Cumulus 1. That functionality is known as "Create Missing" and is found [[Cumulus_Screenshots#File.2FEdit.2FHelp_Menu|within the edit dayfile.txt screen]].
#Only use the editor when Cumulus is '''not''' doing catch-up or end-of-day, or any other action that could create an editing conflict.
#With the contents of the file loaded into the editing table, click the '''Create Missing''' button
#Cumulus 1 will now work through every line from start to end
#If 2 adjacent lines are not for consecutive dates, Cumulus will attempt to create missing lines
#It will read from the [[Standard log files]] all the data logged for each missing meteorological date (if 9am or 10am rollover is used, those read spans two calendar dates)
#It will derive totals, averages, highs, and lows, from the data it reads, for each missing date
#*Note that normally dayfile.txt lines are created from [[Today.ini]] which logs the daily totals, averages, highs, and lows, from every reading taken from the weather station
#*Depending on your weather station, Cumulus is able to read values every minute, and consequently update today.ini each minute if an extreme happens,
#*If Cumulus is set up to only log the readings every half an hour, create missing is only able to see 1/30th of the data,
#* Due to this mismatch, the derived values (averages, highs, lows) this approach can store are much less accurate (hence why getting missing lines from a backup is better)
