I'm trying to use the SCAT2GRID_BIN_XYZT function (using PyFerret or FERRET v7.43). The first call of the function is fine ("stat var4D" in my example below). The problem is when I call the function twice with a new variable ("stat var4D2").
Here is my example :
Let lon = {5, 6}
Let lat = {40,41}
Let deph = {10,20}
Let time = {24112,24113}
Let var = {18, 19}
Let var2 = {17, 16}
Define Axis /X=4:7:0.25 xaxis1
Define Axis /Y=39:42:0.25 yaxis1
Define Axis /Z /Units="m" /Depth /From zaxis1 = {0,5,10,15,20,25}
Define Axis /T=24111:24114:1 taxis1
Let var4D = SCAT2GRID_BIN_XYZT( lon, lat, deph, time, var, X[GX=xaxis1], Y[GY=yaxis1], Z[GZ=zaxis1], T[GT=taxis1] )
Let var4D2 = SCAT2GRID_BIN_XYZT( lon, lat, deph, time, var2, X[GX=xaxis1], Y[GY=yaxis1], Z[GZ=zaxis1], T[GT=taxis1] )
stat var4D
Total # of data points: 4056 (13*13*6*4*1*1)
# flagged as bad data: 4054
Minimum value: 18
Maximum value: 19
Mean value: 18.5 (unweighted average)
Standard deviation: 0.70711
stat var4D2
Bailing out of external function "scat2grid_bin_xyzt":
Input scattered XPTS, ZPTS have different # of points 2 4
**ERROR: error in external function
stat var4D2
What's going wrong?
Thanks for your help,
Bruno
