| Title: | Conversion of Nuclear Magnetic Resonance Spectra in Audio Files |
| Description: | A collection of functions for converting and visualization the free induction decay of mono dimensional nuclear magnetic resonance (NMR) spectra into an audio file. It facilitates the conversion of Bruker datasets in files WAV. The sound of NMR signals could provide an alternative to the current representation of the individual metabolic fingerprint and supply equally significant information. The package includes also NMR spectra of the urine samples provided by four healthy donors. Based on Cacciatore S, Saccenti E, Piccioli M. Hypothesis: the sound of the individual metabolic phenotype? Acoustic detection of NMR experiments. OMICS. 2015;19(3):147-56. <doi:10.1089/omi.2014.0131>. |

Collection of Free Induction Decay of Urine Spectra of the Donor AU
Description
This dataset consists of eigth Free Induction Decay (FID) from eight urine samples. All urine were collected from the donor "AU". The urine are divided in two group; in each group urine samples were collected in a time period of a week. The collection of the two groups is separated by a time course of two years.
Usage
data(AU)Value
A list with the following elements:
sample1A |
a matrix object. FID of the sample 1 of group A. |
sample2A |
a matrix object. FID of the sample 2 of group A. |
sample3A |
a matrix object. FID of the sample 3 of group A. |
sample4A |
a matrix object. FID of the sample 4 of group A. |
sample1B |
a matrix object. FID of the sample 1 of group B. |
sample2B |
a matrix object. FID of the sample 2 of group B. |
sample3B |
a matrix object. FID of the sample 3 of group B. |
sample4b |
