Dear all:

i am having some runtime errors trying to run my program  below: i get an
error like

Exception in thread "main" visad.SetException: SampledSet.init_samples:
sample dimension 1 doesn't match expected length 2

what i am trying to do is to create a flat plane and put spikes on it by
reading the data from a file.
i will be glad if this anomaly can be corrected, i have started compiling a
list of all possible visad errors like the above and their solutions, i will
post it when it gets enough.

see code below:

thanks in advance

Isaac

A2HS_HUMAN      39300   5.43    .16666666666666669
