Check out our wiki and user manual for extensive online documentation.
amica is an interactive and user-friendly web-based platform that accepts proteomic input files from different sources and provides automatically generated quality control, set comparisons, differential expression, biological network and over-representation analysis on the basis of minimal user input.
- Faciliting interactive analyses and visualizations with just a couple of clicks
- DDA: MaxQuant's proteinGroups.txt, FragPipe's combined_protein.tsv
- DIA: Spectronaut's PG report, DIA-NN's PG matrix
- TMT: FragPipe's [abundance/ratio]protein[normalization].tsv
- or any custom, tab-separated file.
- Processed data can be downloaded in a developed amica format which can also be used as input
- Experimental design mapping samples to conditions
- Contrast matrix file for group comparisons in case of MaxQuant, FragPipe or custom upload
- Specification file for mapping relevant columns in case of custom file upload
- Analyzed data downloadable as amica format
- Almost all plots prduced by plotly (hover over plot and download plot as svg or png with the camera icon)
- All plots have customizable plot parameters (width, height, file format, etc.)
- Downloadable data tables
- Remove decoys and proteins only identified by site (MaxQuant)
- Filter on minimum peptide count and spectral count values
- Filter on minimum valid values per group
- Select intensities to:
- (Re-)normalize intensities (VSN, Quantile, Median centering)
- Imputate missing values from normal distribution or replace them by constant value (useful for pilots)
- PCA
- Box plots
- Density plots
- Correlation plots (Pearson correlation)
- Bar plots (identified proteins, % contaminants, most abundant proteins) per sample
- Scatter plots
- Automated QC report
- Primary filter options (log2FC thresholds, multiple-testing correction, select enriched or reduced proteins)
- Analyze single - or multiple selected group comparisons
- Volcano - and MA - plots
- Set comparisons (UpSet plots and Euler diagrams)
- Customizable output data table (can be further filtered)
- Heatmap
- Dot plot
- Fold change plot
- Profile plot
- Protein-protein interaction (PPI) network
- Over-Representation Analysis (ORA)
- Automated Diff. abundance report
- Upload a second amica file from another experiment/analysis to combine datasets
- Download combined dataset
- Correlate intensities from combined dataset (scatter - and correlation plots)
- Differential abundance analysis for combined amica dataset
All dependencies can be installed by executing the install_dependencies.R script.

- Using git and Rstudio
## Clone the repository
git clone https://github.com/tbaccata/amica.git
## Move to the folder
cd amica
## execute install_dependencies.R
## Inside R console or R studio
> library("shiny")
> runApp()
- Using Docker
Have docker installed and running (www.docker.com/get-started)
## Clone the repository
git clone https://github.com/tbaccata/amica.git
## Move to the folder
cd amica
## Build amica, the -t flag is the name of the docker image
docker build -t amica .
## Start amica from terminal
docker run -p 3838:3838 amica
## Open local interface
https://localhost:3838/amica
When deploying a Shiny application with ShinyProxy, the application is simply bundled as an R package and installed into a Docker image. Every time a user runs an application, a container spins up and serves the application.
Detailed documentation is provided here (https://www.shinyproxy.io/documentation/).
A minimum working example based on documentation (https://www.shinyproxy.io/documentation/deployment):
## install docker image for amica (follow the above instructions)
git clone https://github.com/tbaccata/amica.git
cd amica
docker build -t amica .
## download latest version and install it (for debian based systems)
wget https://www.shinyproxy.io/downloads/shinyproxy_2.5.0_amd64.deb
sudo dpkg -i shinyproxy_2.5.0_amd64.deb
## enable system process
sudo systemctl enable shinyproxy
## Add amica into specs part of the server /etc/shinyproxy/application.yml:
## In this file you can also specify the port for shinyproxy.
