 # CycloBranch
 
-An open-source and cross-platform tool for mass spectrometry data analysis.
+An open-source, cross-platform and stand-alone tool for mass spectrometry data analysis.
 
 ## Main features
-  * *De novo* sequencing of nonribosomal peptides.
-  * Compound search (dereplication) in:
+  * designed for identification of small molecules
+  
+  * *de novo* sequencing
+    * non-ribosomal peptides (NRPs) [1]
+    * siderophores (including metals) [2]
+    * supports linear, cyclic, branched, and branch-cyclic structures
+    * based on custom databases of building blocks
+      * 19 proteinogenic amino acids (20 including isomers)
+      * 287 NRP blocks (512 including isomers)
+  
+  * dereplication / database search:
     * conventional mass spectra (MS)
-    * liquid-chromatography mass spectra (LC-MS)
+    * liquid-chromatography mass spectra (LC-MS) [2]
+      * batch-processing
     * imaging mass spectra (MSI)
-  * Image fusion
-  
+      * pixel-by-pixel analysis of imaging mass spectra (imzML) [2]
+      * fusion of imzML files with optical and histology images [3]
+    * tandem mass spectra (MS/MS)
+      * single spectra analysis
+      * supports also a direct comparison of an experimental spectrum with a theoretical one
+    
 ## Supported file formats
   * mzML, imzML
     * profile or centroid spectra
