how to load a spectrum from a dataset with more than 2 columns with spectrum.from_local_file?

[nicocopez]

Normally spectra is saved as two columns (Raman shift, wavelength, etc for the x axis and Intensity for the y axis). However, some software from some systems, for example in the case of the Neegala system of Elodiz, the files are saved with the value for different parameters, followed by a number of columns (I give an example further down). Is there already an option implemented in ramanchada2 to load spectra from such files? I can easily circunvent the problem now that I am looking to a single spectra, but it would be convenient to address this in the future.

Example:

RC2 v0.0.3 should be able to read these files.

import ramanchada2 as rc2
rc2.spectrum.from_local_file('<your-neegala-file.txt>')

It takes Wavenumbers as x-axis and Processed_Data as y-axis. It might be beneficial to use also the rest of the data form the file, but this was never discussed so not implemented.
If there is a problem, it should be fixed.
Let me know

Thank you for the quick reply Georgi.

I get the following error:
ValueError: Some errors were detected !
Line #5 (got 2 columns instead of 1)

Besides, is there any reason why do you choose Wavenumbers? I would asume people working in Raman spectroscopy would go for Raman_shift, or Wavelengths if working with luminescence.

can you make sure that rc2.__version__ is '0.0.3'

[nicocopez]

It took my time, but finally was able to update the version and rc2.spectrum.from_local_file('<your-neegala-file.txt>') did the job, using the Raman shift, for what I can see. Thank you Georgi! :)
