error message
Bram Breure
I'm a newbie Maxent user and I run into problems getting it to work.
I'm using Maxent 3.0.6. beta under MacOSX 10.4.9 (but experienced the
same problem using my old WinXP-machine).
As input I use locality data, exported from a Windows Excel X for Mac
to a CSV-file format. I tried all 3 available CSV-formats (plain CSV,
CSV Windows and CSV 0S/2+MS-DOS) but they all produce error messages:
IOExecption Sample file needs three columns {the locality data are all
listed, the three columns separated by a semicolon (;) instead of a
comma].
Thus, somehow Maxent seems to interprete my CSV-files wrong or it
expects a different CSV-format (??).
When I use a different route, exporting the same data from a Mac-
spreadsheet (Numbers) into CSV-format, the localities are grouped
together at species level (like in the Bradypus tutorial file), but
then the error message is that there is a unused field in the CSV-file
and the species are skipped because it has 0 training samples.
My tentative conclusion is that Maxent is very critical upon the file
format, but currently I have no clue about the cure.
Any suggestion to solve the problem will be greatly appreciated.

Have you tried using commas rather than semicolons as the separator in
your comma-separated value files?

Yes I know that there should be commas as separators and the files
were CSV-files so I guess they should have them. I just can't figure
out if it is the import function in Maxent that doesn't seem to work
or that in both my Excel and Number programs the export-to-CSV-
function is corrupt. That seems to me too odd for an coincidence (?).
