• Use the Results Set Manager to view previous BLAST results, rename and delete results, set up and review Keep Me Posted results.

Note: Fast BLAST is only available if you have already conducted an Explore by Sequence task within the same session.

Name your result set. Then copy/paste the sequence into the entry box, or click Read from File to import the sequence from a file. Click OK.

• Use the sequence input formula that you have. SciFinder accepts standard GCG, FASTA, ASCII text, and SciFinder formats. Numbers, spaces, and other data are ignored.
  
• The Recall Sequence button is active if you have already conducted a sequence search during your session. Use this option to recall a previously searched sequence and quickly start multiple searches using alternate BLAST programs or requirements.

• Select "Referenced in at least one patent document" to only retrieve sequences cited in at least one patent.
  
  Note: A particular sequence may also be cited in other types of documents, in addition to the patent. Therefore, if you later Get References for a sequence (or group of sequences), you will likely retrieve multiple types of documents.
  
• Select "Only retrieve sequences with 50 residues or less" when you are searching short sequences and desire similar length answers. This ensures that SciFinder excludes long sequences, which have a high probability of including your short query sequence.

• Select Show Additional Options to view SciFinder's default BLAST settings.
  
  Note: The default settings are useful for most BLAST searches. However, you may wish to adjust the settings if you are familiar with BLAST searching options. See the SciFinder Help files for information about each of the settings.

• Click a column heading to sort results based on that column. Click the column heading again to reverse the order.
  
  Note: The current sort field and direction are denoted by the arrow in the column heading.
  
• To reorder columns, click and drag a column heading to a new location.
  
• Right-click on a result to see available options.

Click...	To ...
An Alignment Score button	Select the sequences within that score range. Note: Check boxes for those sequences become selected within the Alignment Details area.
An Alignment Summary bar	Jump to the corresponding sequence within the Alignment Details list. Note: Hovering over a bar displays the sequence name.
A "+" button	View Alignment Details for the sequence, e.g., length, score, alignment between the query and result sequences.
A "box" button	View redundant sequences for the grouping.
A Name/CAS Registry Number link	View substance details for the sequence.
Check boxes	Select sequences for further use.

For example, click the + and the box to see redundant sequences and other alignment details.

• Select the check box near the bottom if you are interested in retrieving references that identify the sequence structures as well as studies that discuss activity, disease, and other relationships.
