I am trying to run the second step of quantification (i.e. quantifier) following the mapper module of mirDeep2. In the mapping step everything is fine and I get the collapsed reads to be given to the quantifier module. Then, when trying to run the quantifier module, providing mature, precursor and star sequences, the run ends with an error which apparently lacks any suggestions on where the error is.
Would you please share the data within the context of your Galaxy history? That will capture details of the run that will usually matter when troubleshooting. Meaning: the data, server, tool/version, parameters, command-string, logs. All of the related details about how all of those inputs were consumed by the tool at runtime with context leads to the best actionable help.
