Reprojection Error in Seadas when using some MODIS Aqua L2 files

Hello,

I'm encountering an issue in reprojecting some MODIS Aqua L2 (chl) files using Seadas 7.5.3. Whenever I try to run the reproject tool using some of the nc files (projection: WGS 84, output format: geotiff), the following error is returned:

"An internal error occured during the target product processing.
Type: IllegalArgumentException
Message: [value] is [xxxxxxxxx] but should be in range [0] to [4294967295]"

I'm not sure what the problem is as this only happens to some of the MODIS Aqua l2 files. I don't encounter the issue on most. Can someone please help me and shed light on this? I'm attaching some screenshots for reference.

Thanks...

It seems that the scene wraps the dateline. GeoTIFF gets very confused when the dateline is concerned. You might want to 1) crop the image so it doesn’t contain any data that crosses the dateline before using the reproject feature or 2) use l2bin and then l3mapgen

Also, SeaDAS-8.1.0 was released last month. You are welcome to try it: https://seadas.gsfc.nasa.gov/downloads/

Thanks for the reply, really appreciate it. I'll try l2bin and l3mapgen. :)
