resnet file size

[Patricia Illoldi]

Hi Trevon...

I wanted to ask you if, for running resnet, all the files have to have the same number of cells. This is, we usually cut models to obtain potential distributions, but this means that I can end with files having, for example, 3459 cell, and other with 2345 cells, etc.

Can resnet run using these models, or do I have to leave them will the same number of cells?

Patty,

As I understand it, you are using ResNet to analyze a geographical
region that contains transformed and untransformed cells. It is
assumed that the transformed cells are not suitable as species'
habitat or conservation areas. Two modeling approaches could be used
to analyze such a study region using ResNet. The first approach would
be to construct a ResNet input file that represents the entire study
region, including both the transformed and untransformed cells. The
second approach would be to construct a ResNet input file that
represents the untransformed cells only. As I understand it, you have
one ResNet input file that contains 3459 cells, which represents the
entire study region including both the transformed and untransformed
cells, and a second input file that contains 2345 cells, which
represents the untransformed cells only. As I understand it, your
question is: would it be better to use the ResNet input file with 3459
cells or the ResNet input file with 2345 cells for your analysis?
In my experience, it is better to use a ResNet input file that
contains all of the cells in the study region. At a later stage in
your analysis, you may need to incorporate transformed cells into the
planning exercise. If you use the ResNet input file with 2345 cells
for the preliminary analysis, then it will be more difficult to
compare the results of the preliminary analysis with those of the
analysis of the entire study region that includes the transformed
cells. I recommend that you use the ResNet input file with 3459 cells
and designate the transformed areas as the set of "permanently
excluded cells" in the "Algorithm Options" dialogue box. I would
welcome feedback about how other ResNet users have addressed this
problem.
You might also be asking whether each species in the ResNet input
file must have the same number of cells. The answer to that question
is yes. Each row of the ResNet input file represents one cell and each
column represents one species. The number of columns must be the same
for each row of the ResNet input file.
