Why does HPCA contain 'Neutrophil' and 'Neutrophils'

[PeteHaitch]

Probably one for @friedue.

Looking at how they get broken down in the 'fine' label:

                                         Neutrophil Neutrophils
  Neutrophil                                      3           3
  Neutrophil:commensal_E._coli_MG1655             0           2
  Neutrophil:GM-CSF_IFNg                          0           4
  Neutrophil:inflam                               0           4
  Neutrophil:LPS                                  0           4
  Neutrophil:uropathogenic_E._coli_UTI89          0           1

Should 'Neutrophil' and 'Neutrophils' be one 'main' label or is there a distinction I'm missing?

[friedue]

Nice catch! I'll defer to @dviraran

I'm just going to rename it all to Neutrophils.
