Request from Rick Methot Currently for movement: 1. user specifies which GP, seas, source, dest combinations will have movement 2. parameters are required for each combination selected Shortcomings: 1. movement cannot be gender specific 2. movement rates in a multi-area model cannot be shared Are these shortcomings a big deal for you, or just a minor hindrance? Possible Solution: 1. add gender as a condition for specifying movement 2. add a code for selected movement pattern to each condition 3. then only need to create movement parameters for the N movement patterns 4. this will allow, for example, males and females for a particular source - dest to share the same movement parameters, or not. Also would allow movement rate between area 1 and 3 to share same movement parameters as are used between areas 1 and 2. Similarly for the tag-recapture parameters, I could revise so that you would create a list of unique tag mortality parameters, tag reporting parameters, tag dispersion parameters, etc. Then, each tag group would specify which parameter it was using.
