Error while running SECR

[Shravan Suthar]

Hi all,

I am trying to run SECR to get density estimation for Hyena. In my camera-traps, I got only 4 Hyenas with 19 total capture events (Capture history is attached). The area of study was 47.69 sq km.  I am getting this error. 

Error 1.

Error in makeStart(start, parindx, capthist, mask, detectfn, link, details, : too few values session 1 to determine start; set manually or select different session with details autoini

Error 2. 

> suggest.buffer(caphist_brt2022, noccasions = 19) Error in autoini(object, tempmask, ignoreusage = ignoreusage, ncores = ncores, : too few values for autoini 

 

I believe this could be due to low no. of individual capture or low no. of total capture events.  I had 62 camera-trap locations and and 19 occasions. Can someone please help me to get more clarity on this error and my assumption? it will be really helpful if i can get any other alternative to get the density estimated. 

Thanks and regards,

Shravan
