How many capture events can PRESENCE handle?

Postby not_present » Mon Apr 11, 2016 10:54 pm

I am new to program PRESENCE and occupancy modeling in general. I am using camera trap data to model co-occurrence in a single season, two species model. I have 13,824 capture events. I also have one site-level covariate and two survey-level covariates. PRESENCE crashes any time I try to enter my data. Am I asking too much of the program? Thanks for any help you can offer.

There are no hard-coded limits for the number of sites or surveys in PRESENCE. However, if you try to cut and paste from a spreadsheet, Windows limits the amount of data in the clipboard to 32,000 characters. You might need to cut/paste sections of the input or read the data as a csv file, instead of cut/paste. If you need help or have trouble, you can email the raw data to me (jhines at usgs.gov).
