comment Why do pixel (cell) values change for 32 real NDVI values when taking from Multispec to QGIS?
Thank you for adding that extra information. But you still have not added all the information I suggested - i.e how did you export it from multispec?. However, I can see from that extra information that QGIS has not altered your image. You exported it from multispec (somehow...) as 8-bit unsigned (Byte) format which has data range of 0-255. You have either used the "Processor->Reformat->Change Image File Format" menu and used 8-bit unsigned as the data type, or you have used "File->Save Image To GeoTIFF As..." which only exports in 8-bit...

comment Quantifying amount of sunlight falling in a region
What software do you have? If ArcGIS+Spatial Analyst you can use the Solar Radiation toolset. There are also QGIS+GRASS/SAGA approaches

Can you edit your question again to provide the following information please. What format is the output raster? How did you export it from multispec? Can you provide a gdalinfo report/QGIS metadata properties (open the layer properties from QGIS, click the metadata entry and then scroll down to the properties box, copy that into your question) please.

comment How to build a raster populated with an equation in a python toolbox?
Try using parameters[n].value instead of valueastext so you get the raster objects instead of strings.

comment Data conversion from .bin to ArcGIS GRID file
It's not a esri/envi/etc header file. The header is stored in the first 2880 bytes of the binary file. They're also big-endian. You convert these files with some scripting to generate header/vrt files, but it would be easier to download the tifs instead.

Download the GIS ready tiffs instead - trmmopen.gsfc.nasa.gov/pub/gis

comment mapping.mapDocument() not working, but not throwing exception. path issue?
@Raquel as well as calling mxd.save(), make sure you don't have the mxd open in ArcMap when you run the script in idle.

If gdal can't open your file for some reason it just returns None instead of raising an exception. To see the error, call gdal.UseExceptions() before attempting to open the file

comment Combining rasters to calculate total inputs
@FelixIP while it's in the "reclass" toolset, the lookup tool is not really a reclassification, all it does is make the attributes accessible. The ArcInfo GRID/ArcGIS 8-9 equivalent is raster.attribute and the ArcView 3x equivalent is [raster . attribute].Float (the space around the "." is required, see this answer)
