I am trying to run Maxent and I have processed all layers and converted them into .asc files (all layers have the same resolution and extent), there are no 'No Data' areas within the projection extent and all the sample points overlay the raster layers. 

However, when trying to run the program, the following error appears:

Java.Lang.NumberFormatException: For Input String: "NO DATA_value"

How do i fix this problem? Thanks for your help!

Hi Gregory,
I think the problem could be the space in your file name "University Dissertation", try without space, instead of a space use underscore "University_Dissertation".
I hope this can help you.

Thank you for your help!
However, I tried fixing this and the same error has occurred.
Any other suggestions as to the source of this problem?

How did you create your ".asc" files?

I solved the problem. I have been using QGIS to format and process the environmental parameters. When the raster layers are translated into .asc files it alters the nodata_value. I processed the files through an R script and it worked fine.

Thanks for your help.

Hello 
I had the same problem; Can you tell me which R script you use to solve it ? And if there is another solution than using R ? 

Thank you in advance
