Shows the current balance of cloud computation units and a history of when and how much units have been spent already.
Adds some Blast2GO example data to the Navigation Area to play around with.
This function allows to create a CLC-bio Annotation Table containing the Gene Ontology terms generated with Blast2GO and can be used in combination with Add Annotations in order to perform Hypergeometric Tests on Annotations and Gene Set Enrichment Analysis (Toolbox > Microarray and Small RNA Analysis > Annotation Test).
Remove First Level Annotations
This function removes for each sequence the three main (root or top-level) GO terms (molecular function, biological process and cellular component), if present since they do not provide any relevant information.
This function validates the annotation result and removes redundant GOs from the dataset. It assures that only the most specific annotations for a given sequence are saved. In this way this function prevents that two or more GO terms lying on the same GO branch are assigned to the same sequence. The Gene Ontology "true path rule" assures that all the terms lying on the branch or route from a term up to the root (top-level) must always be true for a given gene product. Therefore, any term is considered as redundant and is removed if a child term coexists for the same sequence.
This function can be run independently, however Blast2GO applies this method automatically always after a modification is made to an existing annotation, such as merging GO terms from InterProScan search, after Annex augmentation or upon manual curation.
This function helps to identify (and optionally delete) sequences from a data-set which are 100% identical.
Set to Sense
Converts sequences with a negative reading frame Top-Blast-Hit to anti-sense i.e. query sequences will be translated to its reverse compliment (e.g. ATTG > CAAT).
Also adds "_antisense" to the sequence name, use Batch Rename to revoke the name change afterwards.
Translate Longest ORF
Converts nucleotide sequences to its longest open reading frame.
Also adds "_ORF" to the sequence name, use Batch Rename to revoke the name change afterwards.
Renames all selected sequences by either adding text or by replacing text patterns (regular expressions can be used). Also allows to convert the sequence names to lower or upper case.
The primary goal of Blast2GO is to assign functional labels in form of GO-terms to nucleotide or protein sequences. However, not only functional labels but also a meaningful description for novel sequences is desired. A common approach is to directly transfer the "Best-BLAST-hit description to the novel sequence. It is frequent that best-hit descriptions are of low-informative text such as "unknown", "putative" or "hypothetical" while descriptions of other Blast hits of the same sequence do contain informative keywords. For this reason, a text-mining functionality has been included in Blast2GO. It analyses a set of sequence descriptions of a given BLAST result. The feature is called the BLAST Description Annotator (BDA). Depending on the frequency of occurrence and the information content, the most suitable description is selected out of the collection of words. In this way, this simple approach avoids sequence descriptions like for example "hypothetical", "putative" or "unknown protein" in the case that a more informative and representative description is available. These descriptions are only of exploratory nature and do not have the same weight of evidence as the functional labels.
