H5Fopen(): unable to open file

[Alexey Yamilov]

Hi everybody,

I was using MPB-package for quite some time already. Everything worked smooth
untill when I tried to input epsilon from a h5-file:

(set! num-bands 10)
(set! geometry-lattice (make lattice
(basis1 1 0)
(basis2 0 1.7) ))

(set! epsilon-input-file "mpb-eps.h5")
(set! grid-size (vector3 20 34 1))
(set! mesh-size 1)
(set! k-points (list (vector3 0 0 0)
(vector3 0 0.5 0)
(vector3 0.5 0 0)
(vector3 0 0 0) ))
(set! k-points (interpolate 8 k-points))
(run-tm)

I have hdf5-1.4.2 and was using it with no problems until now. When I
run mpb, I get HDF5-DIAG message 'unable to open file' (see below).

Any thoughts?

Thanks in advance,
Alexey.

I have hdf5-1.4.2 and was using it with no problems until now. When I
run mpb, I get HDF5-DIAG message 'unable to open file' (see below).

Let me ask the obvious question: is the "mpb-eps.h5" file in the directory
you are in when you run 'mpb', and is it a readable HDF5 file with a
dataset (e.g. 'h5ls mpb-eps.h5' and 'h5topng mpb-eps.h5' should work)?

(Currently, if you run 'mpb foo/bar.ctl' and bar.ctl uses a .h5 input
file, it will look for that file in the working directory, not in foo/,
although I should probably fix this now that I think of it.)

Steven
