## Calculate Molecular Distance Edge (MDE) Descriptors for C, N and O

### Description

Calculate Molecular Distance Edge (MDE) Descriptors for C, N and O

### Usage

    extractDrugMDE(molecules, silent = TRUE)

### Arguments

`molecules` | Parsed molucule object.
`silent` | Logical. Whether the calculating process should be shown or not, default is `TRUE`.

### Details

This descriptor calculates the 10 molecular distance edge (MDE) descriptor described in Liu, S., Cao, C., & Li, Z, and in addition it calculates variants where O and N are considered.

### Value

A data frame, each row represents one of the molecules, each column represents one feature. This function returns one column named `nAtomLAC`.
