Hi,<br><br>I am fairly new to GrADS and I'm trying to compute for vertically-integrated water vapor from my WRF output. I used the VINT function<br><br><blockquote style="margin:0pt 0pt 0pt 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex" class="gmail_quote">
'a = vint(psfc,qvapor,275)'<br></blockquote><br>but I get this error:<br><br><blockquote style="margin:0pt 0pt 0pt 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex" class="gmail_quote">*** glibc detected *** grads: corrupted double-linked list: 0x09c52f88 ***<br>
