Try as I might I couldn't get your script to crash, so I modified my
code so it was more like yours (see below - I've also made some
cosmetic changes as well). It now runs without crashing :)
If you still want to try and squash this bug I'm happy to do some more
testing but as far as I'm concerned the problem is solved.
Many thanks for the help.
Cheers,
John
PS just in case it's at all relevant, I forgot to mention that for
unrelated reasons I'm using matplotlib with numarray rather than numpy
for ani in range(an1, an2):
if ba1 <= ani: ba1 = ani + 1
for bli in range(ba1, ba2):
if v.blank[ani, bli]:
continue
fig = pylab.figure()
ax = fig.add_subplot(111)
for chi in range(v.nch):
ax.plot(v.iat, v.amp[:,ani,bli,0,chi,0], ',')
ax.plot(v.iat, v.amp[:,ani,bli,0,chi,1], ',')
ax.plot(v.iat, v.amp[:,ani,bli,1,chi,0], ',')
ax.plot(v.iat, v.amp[:,ani,bli,1,chi,1], ',')
baseline = '%02d-%02d' % (ani, bli)
ax.set_title('Baseline ' + baseline)
fig.savefig('TimeSeries' + baseline)
pylab.close()
print 'printing baseline ' + baseline
