Abstract:
Thanks to recent advances in sequencing and computational technologies, many researchers with biological and/or medical backgrounds are now producing multiple data sets with an embedded temporal dimension. With various technologies, multiple modalities enable researchers to explore and investigate different biological and physico-chemical processes. Motivated to specifically explore multi-omics data and time-series multi-omics, the exploration process has been hindered by the separation introduced by each omics-type. To effectively explore such temporal data sets, discover anomalies, find patterns, and better understand their intricacies, expertise in computer science and bioinformatics is required. Here we present MOVIS, a modular time-series multi-omics exploration tool with a user-friendly web interface that facilitates the data exploration of such data. It brings into equal participation each time-series omic-type for analysis and visualization. As of the time of writing, two time-series multi-omics data sets haven been integrated and successfully reproduced. The resulting visualizations are task-specific, reproducible, and publication-ready. MOVIS is built on open-source software and is easily extendable to accommodate different analytical tasks.

The data used in the Example 1 comes from the following paper:
Integration of time-series meta-omics data reveals how microbial ecosystems respond to disturbance, Herold, M., Martínez Arbas, S., Narayanasamy, S. et al. Nat Commun 11, 5281(2020). https://doi.org/10.1038/s41467-020-19006-2.
It is stored at Data/cached/example_1/ in either a raw format or as a pickle object.
The data used in the Example 2 comes from the following paper:

Check out our Wiki page for detailed information about MOVIS and how to use it.
The easiest way to install the tool is to use our latest Docker image:
docker pull aanzel/movis:latest
docker run --publish 8501:8501 --detach --name movis aanzel/movis:latest
You can start using the tool by opening a web browser and typing in http://localhost:8501/ as the address. If you run the docker container, you have to use the IP address or hostname instead of localhost.
Caution! Use at your own risk!
You could also clone this repository, build a docker container yourself, and run it locally. This is not recommended as we might introduce unstable features that might not end in the next release of MOVIS. Below is a sequence of instructions (for Linux-based systems) to run the unstable version of MOVIS:
git clone https://github.com/AAnzel/MOVIS.git
cd MOVIS
docker build -t movis-local:unstable .
docker run --publish 8501:8501 --detach --name movis movis-local:unstable
You can start using the tool by opening a web browser and typing in http://localhost:8501/ as the address. If you run the docker container, you have to use the IP address or hostname instead of localhost.
