Fasta read files

The Fasta Read Files importer is designed to import large volumes of read data such as high-throughput sequencing data (NGS reads) in fasta format. Uncompressed files as well as files compressed using gzip (.gz), zip (.zip) or bzip2 (.bz2) can be provided as input. When using the importer, read names can be included but descriptions from the fasta files are ignored.

To launch the Fasta Read Files importer, go to:

        Import (Image Next_Folder_16_n_p) | Fasta Read Files (Image color_ngs_import_16_n_p).

This opens a dialog where files can be selected and import options specified (figure 7.20).

Figure 7.20: Importing data in fasta format.

For import of other fasta format data, such as reference sequences, please use the Standard Import (Image Next_Folder_16_n_p) instead (see Standard import), as this import format also includes the descriptions. To have a reference in track format, please use Tracks (Image import_tracks_16_d_p) and set the "Type of files to import" to FASTA.

This data type can also be imported using the on-the-fly import functionality available in workflows, described in Launching workflows individually and in batches.

The General options to the left are:

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 useful for better organizing subsequent analysis results and for batch processing.
