Have you tried http://code.google.com/p/python-fortranformat/ It's not officially released yet but it's probably worth a try. David H. On Tue, Sep 21, 2010 at 8:25 AM, Andrew Jaffe wrote:

Hi all,

I've got an ascii file with a relatively complicated structure, originally written by fortran with the format:

135 format(a12,1x,2(f10.5,1x),i3,1x,4(f9.3,1x),4(i2,1x),3x, 1 16(f7.2,1x),i3,3x,f13.5,1x,f10.5,1x,f10.6,1x,i3,1x, 2 4(f10.6,1x), 2 i2,1x,f5.2,1x,f10.3,1x,i3,1x,f7.2,1x,f7.2,3x,4(f7.4,1x), 3 4(f7.2,1x),3x,f7.2,1x,i4,3x,f10.3,1x,14(f6.2,1x),i3,1x, 1 3x,2f10.5,8f11.2,2f10.5,f12.3,3x, 4 2(a6,1x),a23,1x,a22,1x,a22)

Note, in particular, that many of the strings contain white space.

Is there a relatively straightforward way to translate this into dtype (and delimiter?) arguments for use with genfromtxt or do I just have to do it by hand?

By hand might be the easiest. If possible, try to put the empty spaces at the beginning of the string (eg, your 3x,f13.5 would be 16 characters). Use `autostrip=True`. Use a sequence as delimiter (like in your case (12,11,11,3,10,10,10,10,3,3,10,8,8,8,8,8,8,8,8,8,8,8,8,8,8,8,4,16...)), that should be more efficient.
