APPRIS ALT2: For genes in which the APPRIS core modules are unable to choose a clear principal isoform, the ALT1 is the candidate transcript(s) models that appear to be conserved in fewer than three tested species.

APPRIS is a system to annotate alternatively spliced transcripts based on a range of computational methods to identify the most functionally important transcript(s) of a gene.

TSL 5: A transcript where no single transcript supports the model structure.

The Transcript Support Level (TSL) is a method to highlight the well-supported and poorly-supported transcript models for users, based on the type and quality of the alignments used to annotate the transcript.

APPRIS P4: Where the APPRIS core modules are unable to choose a clear principal CDS and there is more than one variant with a distinct (but consecutive) CCDS identifiers, APPRIS selects the longest CCDS isoform as the principal variant.

APPRIS is a system to annotate alternatively spliced transcripts based on a range of computational methods to identify the most functionally important transcript(s) of a gene.

TSL 1: A transcript where all splice junctions are supported by at least one non-suspect mRNA.

The Transcript Support Level (TSL) is a method to highlight the well-supported and poorly-supported transcript models for users, based on the type and quality of the alignments used to annotate the transcript.

TSL 2: A transcript where the best supporting mRNA is flagged as suspect or the support is from multiple ESTs
