The submission web application will check for common submission form errors before creating the samples in our Clarity LIMS system. These checks cannot catch everything; getting submissions right at the start is much less work for everyone involved than fixing problems after sequencing.
Refer to the help, and if in any doubt please get in touch with the
Genomics help desk. Take particular care to make sure the indexes are correct when submitting for sequencing only. The Genomics and Bioinformatics cores do not support demultiplexing for a second time to fix incorrect barcodes: that will be your responsibility, for which there is help here.
