hi,

i have some problem trying to run a fortran code. apologies if this is not the appropriate place to post.

i have downloaded the enclosed fortran codes from scatterlib - Project Hosting on Google Code. in a nutshell, these codes calculate light scattering from a spherical particle. i first compile the 2 needed files with

gfortran bhmie.f callbhmie.f

then execute with "./a.out". it is able to run fine, and i can type in inputs. however, when i try to enter a complex number (the complex refractive index), it gives me errors like

At line 33 of file callbhmie.f (unit = 5, file = 'stdin')

Fortran runtime error: bad integer for item 1 in list input

i tried a few different combinations during the input, such as

1.55 -0.008

1.55, 0.008

1.55

but they all give errors similar to the one above. i am not familiar with fortran, but i suspect its the way i input the complex number. anyone knows how i can solve this?

PS: i have started a similar post at [ubuntu] help with a fortran code - Ubuntu Forums

I'm wondering if it's not a compiler directive issue.

You need to read through the program for the inputs. I looked at the FORTRAN program and subroutine and it either prompts for the various inputs or just expects you to know what to input and when to input it. So read through the program CALLBHMIE.F for the read statements and what they require.

thanks for your suggestions. turns out i need to enter

(a, b)

where both a and b are positive numbers.
