Re: grdmath problems

Marcelo:


ShakeMap executes a command similar to this when it runs:

/usr/src/gmt-4.5.11/bin/grdmath
/opt/shakemap2/bin/../data/9583161/richter/pgv_rock.grd DUP DUP 10 LE 0.65
MUL EXCH DUP DUP DUP 10 GT EXCH 20 LE MUL EXCH 10 SUB 10 DIV -0.05 MUL 0.65
ADD MUL EXCH DUP DUP DUP 20 GT EXCH 30 LE MUL EXCH 20 SUB 10 DIV -0.07 MUL
0.60 ADD MUL EXCH DUP DUP DUP 30 GT EXCH 40 LE MUL EXCH 30 SUB 10 DIV -0.08
MUL 0.53 ADD MUL EXCH 40 GT 0.45 MUL ADD ADD ADD ADD 686
/opt/shakemap2/bin/../data/9583161/output/UFVS74PC0J.grd DIV EXCH POW MUL =
/opt/shakemap2/bin/../data/9583161/output/pgv.grd

causing the buffer overflow message to appear.

but in this case the complete path is given to the equivalent of "1.grd" in
previous examples: /opt/shakemap2/bin/../data/9583161/richter/pgv_rock.grd

This is analogous to giving the full path to 1.grd as /home/osop/1.grd. So
what might be going on? pgv_rock.grd definitely exists at the time of
execution. Otherwise you would get this error:
grdmath: GMT SYNTAX ERROR:
/opt/shakemap2/bin/../data/9583161/richter/pgv_rock.grd is not a number,
operator or file name
