Re: Segmentation Fault

Hi Mike,

The output you show is from ncl5.2.1, and it certainly makes sense (e.g., the Total size field reporting "-421147456 bytes"
Can you post the results of the same commands entered into V6.0.0 ?'
What do you mean by "read the data in as a whole"?

Thanks,
Rick

I have built large-files consisting of Jan 1989 - September 2011 data, and am able to read the data in as a whole, but when I try to read the first latitude point in, I recieve a segmentation fault. I recieve segmantation faults for both v5.2.1 and v.6.0 of NCL. Would you be able to attempt to help me understand what is going wrong?
