I have an error while trying to change the output of the mosaic_doit function to a tiff file. It out puts a dat file which is not working with various python functions I need it to. This is the approach I took right now. envi_doit exports out a .dat file. Let me know if there is any other way or if there is something else that I can do to fix this.
envi_doit, 'mosaic_doit', fid=mfid, pos=mpos, $ dims=mdims, out_name=out_name, xsize=xsize, $ ysize=ysize, x0=x0, y0=y0, georef=0,MAP_INFO=map_info, $ out_dt=Data_Type, pixel_size=pixel_size, $ background=0, see_through_val=see_through_val, $ use_see_through=use_see_through envi_output_to_external_format, DIMS= 0, fid = mfid, out_name = "E:\Abhi\desktop\testing\Small script testing\rasters\raster.tif",tiff = tiff

MOSAIC_DOIT will only output to ENVI format (.dat) files. You need to use the returned fid from this routine (r_fid) to pass to ENVI_OUTPUT_TO_EXTERNAL_FORMAT with the /TIFF keyword. For example:
envi_output_to_external_format, DIMS=dims, fid = r_fid, out_name = "E:\Abhi\desktop\testing\Small script testing\rasters\raster.tif", /tiff
It also looks like the DIMS are set to 0 when converting to TIFF. The dims should be the dims returned from the mosaic result. You can do a file query on the result (using the r_fid returned from mosaic_doit) to get the DIMS of the new file in case the dimensions have changed from the original input files of the mosaic.

Thanks for the reply, I tried changing it to this:
envi_doit, 'mosaic_doit', fid=mfid, pos=mpos, $
dims=mdims, out_name=out_name, xsize=xsize, $
ysize=ysize, x0=x0, y0=y0, georef=0,MAP_INFO=map_info, $
out_dt=Data_Type, pixel_size=pixel_size, $
background=0, see_through_val=see_through_val, $
use_see_through=use_see_through, R_fid = R_fid
outtif= strmid(outfile, 0,19)
outtif = outtif + 'tif'
output = "E:\Abhi\desktop\testing\Small script testing\rasters\" + outtif
envi_file_query, fid = R_fid, dims = TDim
envi_output_to_external_format, dims= TDim, fid = R_fid, out_name = output,/tiff
This does not work though, What am I doing wrong?

Do you get an error compiling? Is it failing in the mosaic or the TIFF output?
The syntax for ENVI_FILE_QUERY is to pass the fid as a parameter and not a keyword. For example:
envi_file_query, r_fid, dims=r_dims

It is not failing anymore, instead it is creating a tif that is only 1kb large.
Here is the updated script:
envi_doit, 'mosaic_doit', fid=mfid, pos=mpos, $
dims=mdims, out_name=out_name, xsize=xsize, $
ysize=ysize, x0=x0, y0=y0, georef=0,MAP_INFO=map_info, $
out_dt=Data_Type, pixel_size=pixel_size, $
background=0, see_through_val=see_through_val, $
use_see_through=use_see_through, R_fid = R_fid
outtif = strmid(outfile, 0,19) ;+ '.tif'
outtif = outtif + '.tif'
output = "E:\Abhi\desktop\testing\Small script testing\rasters\" + outtif
envi_file_query, R_fid, dims = r_dim
envi_output_to_external_format, dims= r_dim, fid = R_fid, out_name = output,/tiff

It is unlikely that it is the conversion to TIFF that is the issue.
Is the mosaic image correct? What is the size of the ENVI file it creates?

The .dat files are all 8mbs each and load perfectly well in ENVI. I must be doing something wrong in the two lines below the Mosiac function
