not opening my h5 file :-( "the file is not witable" #5

Closed e-lo closed 11 years ago

e-lo commented 11 years ago

Issue Part 1 : call to pytables to open h5 file is returning an error that it isn't writable (FileModeError) despite there not being any permissions or read-onlyness of the file

Issue Part 2: why are we requiring write file privies if we are opening as read-only?

testTA.py:

import omx,numpy

TEST_FILE = r"testData/sfptam.h5"

myfile = omx.openFile(TEST_FILE, 'r')  

Traceback:

C:\work\omx>python testTA.py
Traceback (most recent call last):
