Hi all,
I am attempting to use program DENSITY 5.0 for the first time and I am having difficulties having the program read my capture data text file. I have checked the forum postings and help files and cannot seem to figure out what I am doing wrong. I am getting the following error:

Capture file contains record of ID 138 in session 1 with trap ID SB8 (sample 2) that is not in trap site file.

I double checked the trap file and it does indeed have trap SB8 (see below). Furthermore, when I delete this entry from both files, I get a similar message for another ID.
Here is a snippet of my capture file:
# session, animal ID, occasion, trapID
1 364 2 SF-11
1 198 2 SX3
1 345 2 SJJ-10
1 138 2 SB8
1 432 3 SVV4
1 345 3 SJJ-10
1 415 3 SJJ-4

Here is a snippet of my trap file:
#Trap ID, x, y
Sb6 417101 4804675
Sb-6 417095 4804863
Sb7 417101 4804659
Sb-7 417095 4804879
Sb8 417101 4804642
Sb-8 417093 4804896
Sb9 417101 4804626

My trap file seems to be working fine as I was able to use it in the simulator. Any suggestion as to what I might be doing wrong would be greatly appreciated.

Best regards,

Eric

Case sensitivity? Capture file is in capitals while trap file is in lower case, for all entries.

Thanks, James! That was it. I thought I read somewhere that the text file source data were not case sensitive. Obviously, I was mistaken. Thanks again!

Hmm. The Help does say "Density is not case-sensitive", but a bug may have slipped into 5.0. I'll have to look into that.

I can confirm that Density is case-sensitive with respect to TrapID in both the trap layout and capture files, and that this is a longstanding bug (at least 4.4 and 5.0). Funny that it hasn't caused problems before. I suggest we just live with it until there's a strong reason to put out a new version. Other identifiers are converted to uppercase internally. Thanks for spotting this, James.

Hi Murray,

Thank you for looking into the matter and for making me aware of the bug. The case sensitivity is easy enough to work with, but I was initially a bit perplexed as to why I couldn't get the program to read my capture text file. Thanks for clearing things up.

Cheers!

Eric
