Thanks for the quick reply. Feel stupid now! So I changed my code, yet now get errors associated with "esps1" " Parsing parameters: --project=skt --job=denovo,est,normal,454 454_SETTINGS,esps1 , ========================= Parameter parsing error(s) ========================== * Parameter section: '(none)' * unrecognised string or unexpected character: esps1 ============================================================================ === Fatal error (may be due to problems of the input data or parameters): "Error while parsing parameters, sorry." ->Thrown: void MIRAParameters::parse(istream & is, vector<MIRAParameters> & Pv, MIRAParameters * singlemp) ->Caught: main Aborting process, probably due to error in the input data or parametrisation.
