BSQ to TIF conversion; Output pixelated

[SarahNiemczura]

Hello, I was wondering if anyone can help me with an issue I'm having. I have a .bsq that I would like to convert to a .tif file however the output is turning out pixelated and the values are completely wrong.

Any thoughts on how to correct this??? It's been awhile and I'm out of ideas; I've check the coordinate systems, I've even tried copying raster, exporting raster... all the same result.

Thanks.
