In order to analyze your data, we require a Meta Data file as a .csv which contains information about your data and groups
The link below provides a sample Metadata file we have created for demonstration purposes.
The Metadata File is a comma seperated values file (.csv) with a minimum of 2 columns.
- The 1st column is required to be named ‘File Name’ and needs to contain the names of the untargeted metabolomic data files to be used in the analysis.
- All additional columns are covariates associated with your untargeted metabolomic data files, however only 3 can be used at a time for analysis in the free version.
If you need additional assistance in creation of you metadata file, please do not hesitate to contact us.
If your experiment collected measurements on subjects multiple times. You can analyze your data using the ‘Group Comparison with Repeated Measures’ study design. This will take into account samples coming from the same subject multiple times.
If your experiment collected and ran samples in batches(different times). You can analyze your data using the ‘Group Comparison with Batch Adjustment ’ study design. This will take into account samples being run at different times.
Our software allows for multiple metadata files to be uploaded per dataset. In order to test multiple hypothesis on the same dataset
The file below shows another sample metadata file that was editted from the base metadata file. The difference is that there are now only 8 samples from 2 different treatments. Therefore, an analysis using this metadata file will look for features that are significantly different between the 2 groups of ATP and Control.
This metadata file can be uploaded and used with the full sample dataset of 16.
The following image displays 3 uploaded metadata files for a single data set on the ‘Upload Data’ page.
