Hi, No, likely you have not forgottten anything. You have bound crt to loop and chances are your station provides what are known as partial packets, ie each loop packet does not contain all observations, so when the crt service receives a loop packet it does not have values for all obs and those that are missing are None/NULL etc. If that is the case you essentially have three choices; change your binding from loop to archive but then crt will only generate files every archive interval, you can live with it or get another station that does not have partial packets. What station do you have ?
