Matplotlib dateutil bug

Forced creation of a TOC - this will improve the formatting on the main page 'Did you know...' section.

__TOC__

== Background ==

When you create a range in relax, it is created as an xrange object.<br>

This is due to memory issues, which you can read about [http://thread.gmane.org/gmane.science.nmr.relax.devel/4862/focus=4865 here.]

You cannot by default slice through xrange objects.

The '''dateutil.rrule''' package (version 1.5) used in matplotlib/pylab creates some list, which it expects it can slice through.<br>'''dateutil.rrule''' package (version 2.2) does not have this problem.

But relax will create these as '''xrange''' which is not-sliceable.

== Change bug in dateutil.rrule ==

The recommended way is to update your version of the '''python-dateutil''' package.

sudo pip install python-dateutil --upgrade

</source>

If you by some means need to stay with the current versions, you can try.

bash

echo $MFILE

sudo sed -i -e 's/range(1,30), range(1,31), range(1,32)/list(range(1,30)), list(range(1,31)), list(range(1,32))/g' $MFILE

sudo sed -i -e 's/range(-29,0), range(-30,0), range(-31,0)/list(range(-29,0)), list(range(-30,0)), list(range(-31,0))/g' $MFILE

</source>

Test if it worked

~~$ relax~~cat <<EOF > relax_test.py~~relax>~~ from pylab import * t = arange(0.0, 2.0, 0.01)s = sin(2*pi*t)plot(t, s) xlabel('time (s)')ylabel('voltage (mV)')title('About as simple as it gets, folks')grid(True)show()EOF

relax relax_test.py

</source>
