Hello,
This could be a couple of things. First of all, I should say that that
bit of the code with the error message is all about doing a random sample
of the data to try and estimate the noise level of the spectrum. Since
it's random it means that if something is going wrong then the exact point
is likely to differ from attempt to attempt.
That point (201 390 493) is pretty big. So just that number implies a
data file that should be at least 150Mb in size (and probably much
bigger). So has the data file been truncated perhaps?? We should
probably check the data file size against the number of points so we don't
get this obscure error.
And I should say that for a large 3D data set like this, NmrPipe format
will normally not be a good one to use because (at least the examples I've
seen) it is not blocked, which makes access pretty slow (that might be
what you are observing), especially in the dimensions other than the
first.
