[mesa-users] Differences between profile and FGONG file

[Liliana Novais]

Thanks Earl, my problem is that I cannot extract the values from the 
file my colleague says my file is wrong. On the top of the file instead 
of 1300 it should be a 300, according to him. Can you tell me which 
program you used to extract the data.

Regards,

Liliana
