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 [[ | 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.

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. | ||

[[File:Badge vMx.png]]The beta versions of MX did not include any feature to view or edit dayfile.txt, so any checking or editing had to take place outside the software. As mentioned above, MX does not provide any way to read, or calculate, values from any other file, nor will it do bulk edits. For any of these, you will need to take a copy of the Cumulus file and manipulate using a script or a spreadsheet processor. Do be careful not to change the encoding, the position of line feeds, the format of any field, the locale, or anything else that might stop MX being able to read the file. | [[File:Badge vMx.png]]The beta versions of MX did not include any feature to view or edit dayfile.txt, so any checking or editing had to take place outside the software.
