Hola Francesc,
I'm trying to combine EArray nodes from two separate files into a single
file. The problem seems to be with the append method.
>>> print tables.__version__
1.3
>>> print numarray.__version__
1.5.1
>>> master = tables.openFile('heck1.h5', 'a')
>>> node = master.root.results.ogpfb1.appload
>>> node
/results/ogpfb1/appload (EArray(124L, 6952L, 6L), zlib(6)) ''
atom = Atom(dtype='Float32', shape=(0, 6952L, 6L), flavor='numarray')
nrows = 124
extdim = 0
flavor = 'numarray'
byteorder = 'big'
>>> fh = tables.openFile('heck2.h5')
>>> bigbuf = fh.root.results.ogpfb1.appload[:]
>>> bigbuf.shape
(123, 6952, 6)
>>> node.append(bigbuf)
>>> node
/results/ogpfb1/appload (EArray(247L, 6952L, 6L), zlib(6)) ''
atom = Atom(dtype='Float32', shape=(0, 6952L, 6L), flavor='numarray')
nrows = 247
extdim = 0
flavor = 'numarray'
byteorder = 'big'
>>> assert node[-1,-1,-1] == bigbuf[-1,-1,-1]
Traceback (most recent call last):
File "<stdin>", line 1, in ?
AssertionError
>>> bigbuf[-1,-1]
array([ -1.51880996e+04, 1.79550003e+02, -2.02230005e+03,
1.89211500e+05, -1.05684000e+05, -2.11816500e+05],
type=Float32)
>>> node[-1,-1]
array([ 2.46069298e+23, -2.94021216e+08, -8.35400165e-23,
-1.14265963e+20, 9.80874033e-39, 3.69827696e-19],
type=Float32)
I end up with the correct shape, but the data is corrupt. I can work
around this by using numarray.concatenate and then just create a new node,
but if you have any idea what I'm doing wrong, I would love to have your
input. Btw, the files were not created by PyTables.
PyTables 1.3
