I think that I have found the problem, and it is the omission of a single
'=' sign!

Do the following:

<as 'mcidas'>

cd ~mcidas/mcidas2017/src

-- edit scmiutil.c

   On line 1974 change:

        if ( diff_lon < 0 ) {                   /* grid origin east of lon_s  */


   to:

        if ( diff_lon <= 0 ) {                   /* grid origin east of lon_s  
*/

   exit out of your editor saving changes

make libsdi.a scmiadir scmiaget && rm ~/bin/scmia* && ln scmiadir scmiaget ~/bin

I have made the change to scmiutil.c on lead.unidata.ucar.edu, and
the change will be in the v2017b release after I have included SSEC's
v2017.2 XCD mods.

Please let me know your results!

Cheers,

Tom
