Omics Data Analyser
This is an R program to visualize, normalize, and analyze -omics data such as those from metabolomics and proteomics experiments. Data are supplied as a list or table along with parameter settings, all in an Excel file.
Current version: 1.7.1. Tested R version: 3.5.1
How to run this tool:
Step 1: Download all files from this website and save them all in a folder.
Step 2: Make a copy of the data template file and open it in Excel. Read the instructions in there. Make sure Excel Macros are allowed.
Step 3: Copy your data to the RawData sheet of the template. Data can be a list or table with samples, features, feature descriptions and values. See data template for details.
