Steps for correcting camera start/stop times. You have already done the first two steps.
(1) Download CorrectInputFile.exe from http://www.smallcats.org storing it in the same folder with allthe other programs.
(3) Download the library file pg.dll from http://www.smallcats.org storing it in the same folder.
(4) Make sure AllPictures.txt and Input.txt are present in the folder.  CorrectInoutFile uses AllPictures.txt
(5) Copy Input.txt as InputOld.txt.  THis preserves your UTM and elavtion data already netered.
(6) Double-click CorrectInputFile
(7) Let CorrectInputFile run to completion. Open and inspect DateList.txt.  Copy the last lines and paste them into Input.txt over-writing the camera trap start-stop information entirely.
(7) Save this file InputTemp.txt and using InputOld.txt run program UpdateInput.
(8) Inspect InputNew.txt.  If it looks good, change its name to Inout.txt and run the analysis.
