Attempting to mask raises ValueError #17

When I put the keyword mask in the parameter file and run VoigtFit, I get the following error:

Traceback (most recent call last): File "/usr/current/anaconda/bin/VoigtFit", line 11, in <module> sys.exit(main()) File "/usr/custom/Anaconda/lib/python2.7/site-packages/VoigtFit/VoigtFit.py", line 522, in main dataset.mask_line(line_tag, reset=False) File "/usr/custom/Anaconda/lib/python2.7/site-packages/VoigtFit/dataset.py", line 628, in mask_line region.define_mask(z=self.redshift, dataset=self, telluric=telluric) File "/usr/custom/Anaconda/lib/python2.7/site-packages/VoigtFit/regions.py", line 283, in define_mask plt.plot(wl_T, (flux_T/flux_T.max() + 1.2)*cont, color='orange', alpha=0.7, lw=0.5) File "/usr/custom/Anaconda/lib/python2.7/site-packages/numpy/core/_methods.py", line 26, in _amax return umr_maximum(a, axis, None, out, keepdims) ValueError: zero-size array to reduction operation maximum which has no identity

If I run VoigtFit without attempting to mask, it works fine.

Hi, sorry for the late reply. What line (or lines) are you trying to fit? And at what redshift?

The bug has been fixed in the latest version of the code.
