Note! During import, partial adapter sequences are removed (TCAG and ATGC ), and if the full sequencing adapters GCCTTGCCAGCCCGCTCAG , GCCTCCCTCGCGCCATCAG or their reverse complements are found, they are also removed (including tailing Ns). If you do not wish to remove the adapter sequences (e.g. if they have already been removed by other software), please uncheck the Remove adapter sequence option.

Click Next to adjust how to handle the results). We recommend choosing Save in order to save the results directly to a folder, since you probably want to save anyway before proceeding with your analysis. There is an option to put the import data into a separate folder. This can be handy for better organizing subsequent analysis results and for batch processing.
