# MSDtracking

R and Python code to analyze BRCA2-HaloTag single-molecule tracking data

For tracking the SOS Plugin [1] (http://smal.ws/wp/software/sosplugin/) is used.
Track segmentation and MSD analysis is done using the DLMSS method [2]

Data is imported from folders with csv files using 'scripts/analysis script v2.R' and track segmentation is done using 'analyze_MLMSS.R' a adapted script that allows to do DLMSS analysis directy from RStudio, using the Reticulate package.

The package can be installed in R Studio (www.r-studio.com)

```R
install.packages("devtools")  
library(devtools)  


install_github("maartenpaul/DBD_tracking")

library(DBD_tracking)  
```
