mz.ppm.thr | The threshold for m/z error calculation. |
path | Work directory. |
width | The width of MS2 spectra match figure (inch). |
height | The height of MS2 spectra match figure (inch). |
interaction.plot | Output interactive plot or not. |
range.mz | m/z range for MS2 spectra match plot. |
range.int | Relative intensity range. |
xlab | Title of x axis. |
ylab | Title of y axis. |
col.lib | Colour of database MS2 spectrum. |
col.exp | Colour of experimental MS2 spectrum. |
title.size | Font size of title. |
lab.size | Font size of title of axis. |
axis.text.size | Font size of axis text. |
legend.title.size | Legend title size. |
legend.text.size | Legend text size. |
figure.type | "pdf" or "png". |
threads | The number of threads |
one.folder | Output all figure in one folder or not. |
show.plot | Show plot or just save them. |
A or all ms2 match plot(s).
