[pymvpa] Advice for input to SampleAttributes? Text file may have too many columns?

Hello all,

I'm having trouble passing a text file to SampleAttributes, and I -think-
what my problem might be is that my text file has more columns than I
thought it did. Vim seems to think it has 3894 columns. I have a couple
questions. Does the following error message seem consistent with this? And
if so, is there a possible way to fix this? Even better, is there a way to
read in an Excel spreadsheet? That's the file format I'm starting with.

>>> attr = SampleAttributes(attr_fname)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/lib/python2.7/dist-packages/mvpa2/misc/io/base.py", line 426,
in __init__
    sep=None, dtype=dtypes)
  File "/usr/lib/python2.7/dist-packages/mvpa2/misc/io/base.py", line 118,
in __init__
    dtype=dtype, skiplines=skiplines)
  File "/usr/lib/python2.7/dist-packages/mvpa2/misc/io/base.py", line 258,
in _from_file
    "of columns in header [%i]." % (len(l), len(hdr))
RuntimeError: Number of entries in line [3] does not match number of
columns in header [2].

Thanks for your help!
