An R package for the (3D) visualisation and analysis of biological image data, especially tracings of
single neurons. **nat** is the core package of a wider suite of neuroanatomy
tools introduced at http://natverse.github.io. **nat** (and its ancestors)
have been used in a number of papers from our group including:

For the impatient ...

```
# install
install.packages("nat")
# use
library(nat)
# plot some test data (?kcs20 for details)
# Drosophila Kenyon cells processed from raw data at http://flycircuit.tw
head(kcs20)
open3d()
plot3d(kcs20, col=type)
# get help
?nat
```

A confirmed stable version of **nat** can be installed from CRAN.

```
install.packages("nat")
````
However, **nat** remains under quite active development, so if you will be
using **nat** extensively, we generally
recommend installing the latest development version directly from github using
the [devtools](https://cran.r-project.org/package=devtools) package.
```r
# install devtools if required
if (!requireNamespace("devtools")) install.packages("devtools")
# then install nat
devtools::install_github("natverse/nat")
```

To get an idea of what **nat** can do:

- Skim through the Articles listed at https://natverse.org//nat/
- Take a look at the R Markdown reports used to generate the figures for our NBLAST paper.

When you're ready to learn more:

- Read the overview package documentation
(
`?nat`

in R) - Read the Introduction to neurons article
- Check out the thematically organised function reference documentation.
- Most help pages include examples.
- Try out sample code:
- nat.examples has detailed examples for data sets from a range of model organisms and techniques
- frulhns analysis of sexually dimorphic circuits
- NBLAST figures

If you want some help using **nat**:

- For installation issues, see the Installation vignette
- Contact nat-user Google group - we normally respond promptly and you will also be helping future users.

If you think that you have found a bug:

- Install the development version of nat using devtools (see above) and see if that helps.
- Check the github issues and
- file a bug report if this seems to be a new problem
- comment on an existing bug report
