New version of ENMTools up

I've tracked down the sorting bug that Rich and I found last night, and there's now a new version of ENMTools that fixes the issue. It does appear that it only affected the ribbon analysis, and only the sorted output. There are some new functions added as well. One is just a simple tool for measuring correlations between raster files using the Pearson correlation coefficient. The second gives you the ability to sample occurrences from a raster file either randomly or with a probability determined by some function of the suitability of habitat in that grid cell. You can download the new version and manual here. There's more information on the new functions in the manual.

Now that the application note is out we're going to start using actual version numbers instead of build dates. This is version 1.1.

Sorting bug with ribbon range-breaking analysis

It has just now come to my attention that ENMTools has a bug involving the sorting of I and D values for the ribbon range-breaking analysis. This bug can cause incorrect values to be inserted into the sorted output. The unsorted output files are still fine, and as far as we can tell at the moment this bug doesn't apply to any other analysis. If you are using the ribbon analysis, please use the .csv files for the unsorted output and sort them in Excel yourself. I am working on this bug right now and will post a corrected version of the software ASAP. My apologies for any inconvenience this might have caused.

Problems with ENMTools and Maxent 3.3.2

Rich and I just hit a problem, but luckily it's one with an easy solution.

As discussed on the Maxent discussion group, Maxent version 3.3.2 does not necessarily like underscores too much. Since ENMTools generates replicate names using underscores, this leads to replicates crashing, often with "number format exception" messages from Maxent and "Can't open ..." messages from ENMTools. Steven is aware of the issue and is working on it, but for now we'd suggest sticking with version 3.3.1 for your ENMTools runs.
