I am trying to use ASICS for analysis of my NMR spectra.

spectra_data <- importSpectraBruker(name.dir = "C:/Spectra/NMR/Must test", sample.names = NULL, ncores = 6, ppm.grid = NULL, verbose = TRUE)

When imported, they show only 31087 points whereas all my spectra have 65536 points. I suppose it has something to do with the "ppm.grid" parameter.

It is said in the manual that is is

"Numeric vector of a unique grid (definition domain) for all spectra (in ppm). Default to NULL (in which case, the default grid of the pure library is used)."

How can I change the ppm.grid so all 65536 points will be imported?

Thanks in advance
