Re: [ferret_users] nc2mc.sh

Hi,
Thank you for your answer. I once used fortran program
to make .mc file before, it works on other nc files.
However, I check my current .nc files and found the
name of time axis of many nc files is different. I
think I need to unify the name (use the same axis in
the same name, x,y,z,t), then all these errors will
definitely avoid.
I have a way to change the axis name: first change cdf
files into ascii, then redefine the name of axes. But
it takes long time because I have about 1400 nc files,
each file has a size about 380MB. Do you have a method
that will change the name of axes within cdf file so
that I can save a lot of time?

Thank you so much!
