Modomics - A Database of RNA Modifications

Advertisement

To the users' knowledge, some UNICODE characters previously used to represent modifications along RNA sequences have been changed. Special characters like ',=,+ etc. or any other special character causing problems in software like excel, python, notpad++ or other text editors, have been changed. Their new version is highlighted with a different color than before in the RNAMods new column.
