m-array does not show removed animals

[twhb]

I used the removed individual instructions from "A gentle Introduction" and discovered the following:

1) If the proceeding 1 are not replaced with 0's then the removed animals are added to the total released.

2) When I placed a -1 on the individual removed at the appropriate occasion, it did not show up in the m-array. It appears the individual numbers are not subtracted from proceedure.

The data:
Occasion Released, removed, What Marked indicated
1 2028 , 0, 2028
2 82, 2 , 84
3 90 , 2 , 92
4 99 , 5 , 104
5 80 , 3 , 83

Does any one have a suggestion?

Thank-you

Based on what you wrote in your post, my impression is that you're placing the "-1" in the the encounter postion of the encounter history rather than the grouping section? For example, using the recaptures only data type (CJS/live encounters) and a single group, one possible encounter history (EH) is

10100 1;

If this animal was removed on the last encounter (occasion 3) the correct format is

10100 -1;

If instead you built your EH as

10-100 1;

then I suspect mark would view "-1" as non-zero and include the animal in the release counts that you mentioned in your post. I suspect mark doesn't care that it is 1 or -1 or 2 or possibly even A or B - if you specifiy the recaptures only data type mark counts an animal as not seen = 0 and seen = any other character. So, if my initial impression from your post is correct, then your results are what we would expect and all you need to do is to specify the "-1" in the group section of the EH; after which the release counts will be inline with what you observed.
