<![CDATA[
This tool will lookup files on the Galaxy server machine, including mounted directories.

Only directories that are included in the white list and not in the black list are allowed.
If the directory you require does not pass the white list or blacklist test please contact the local galaxy admin.
(Admins see README)

This tool only supports a limited set of types and file extenstions. 
No other files are ever returned either by data or listing.
These endings are case senitive.

====

The data options will look for all files that have a particular ending in the selected directory.

The tool will return two things.

1. A Dataset collection of all the detected files.

2. A file with the names of all the detected files. These will be sorted in the same order as galaxy builds the dataset collection. 

The files can be filtered by setting a specific start strinf for the file name. 
Only files that start with this string (case senstive) will be included.

Files can also be filter for the last part before the file extsentions.

Assuming the directory has:
C01_R1_001.fasta   C01_R2_001.fatsa   C02_R1_001.fasta   C02_R2_001.fatsa

Setting start C01 will return just the C01 files:   C01_R1_001.fasta   C01_R2_001.fatsa

Setting last R1_001 will return the read1 files:   C01_R1_001.fasta   C02_R1_001.fasta

As Galaxy detects the file type based on the extension this tool will change the exstension for supported alternative file ends.
    This includes (manually) setting the exstension to fastqsanger, fastqsolexa, fastqillumina for tools that specify one of these.

This tool will unzip gz files.

====

The listing option will return a txt file with all the files found with any of the supported endings. Other files in that directory are not included.

The file exstensions are left as in the directory.

File start and last filters are not supported in this mode.
