Hello Jianguang,
Setting the type during loading from the FTP area into a history as a
dataset is optional. Through experience, I believe that this helps to
speed up the process, but this is purely anecdotal.
For datasets that have been imported, but have not had format
auto-detected, or the format detected was incorrect or not specific
enough (e.g. fastq when you want fastqsanger), just edit the
dataset's attributes. Click on the pencil icon in the upper right corner
of any dataset, click on the dataset tab in the form that comes up in
the middle panel, pick the type from the menu, and save.
This can be done with any dataset, at any point. After running certain
tools, reassignment of datatype or other metadata (column assignments,
found on the first tab of the same Edit Attributes form above) is
needed - often the tool will note if this is the case.
Galaxy has some logic that will prevent the misalignment of obviously
incorrect metadata - including widely inappropriate datatypes. But
tuning the type to be specific and correct between a group of common
format datatypes (for example: a group like tabular, bed, interval)
would be for you to ensure.
Setting database is also optional and can be performed during or after
loading, or at any other time, by clicking through the pencil icon on
Edit Attributes form (first tab).
In most cases - skip converting spaces to tabs - unless you really are
working with a strict tabular dataset and are certain that no fields
contain internal whitespace (including informative/metadata headers).
Hopefully this helps,
Jen

Hi Everyone,
When I upload my datasets onto my history via FTP method (using
FileZilla), do I need to specify the file format under File Format
of Upload File from your computer?
I noticed that the screencast of how to upload datasets via FTP just
leaves the File Format as Auto-detect. However, I also noticed
this sentence in the help for Auto-detect: the system will attempt to
detect Axt, Fasta, Fastqsolexa, Gff, Gff3, Html, Lav, Maf, Tabular,
Wiggle, Bed and Interval (Bed with headers) formats. Do I need to
specify the format of my datasets if the format of my datasets is not
listed in the sentence above?
Thanks.
Jianguang
