IIN with MS-DIAL¶
In MS-DIAL can process LC-MS/MS data performed in non-targeted mode, but also in MSE and now with Ion Mobility Spectrometry. After the processing the Supplementary Pairs file can be exported and used for IIN.
Development and Installation¶

Running the FBMN IIN workflow with MS-DIAL¶
The integration of MS-DIAL and IIN is supported since version 4.1 and support for FBMN from version 2.99. After a standard processing data with MS-DIAL, the “Alignment results” can be exported for IIN analysis.
Step 1: Process your non-targeted LC-MS/MS data with MS-DIAL following the FBMN documentation guidelines.
Step 2: After processing your data export the Supplementary Annotation/Pairs files from the "Alignement results" using the option “GNPS export” and “Export GNPS edge files”.
For visualizing results in Cytoscape. Please refer to the main FBMNxIIN documentation.
See our MS-DIAL tutorial on using Feature Based Molecular Networking for the American Gut Project sample.
