The classify and filter tools output a txt file containing isoform annotation information. The output from classify and filter will have the extensions
_classification.filtered_lite_classification.txt respectively. Both of these outputs follow the SQANTI3 classification file convention with the exception of two added columns.
|FL count associated with the isoform including PCR duplicates.
|Comma separated list of unique cell barcode ids associated with the isoform.
Sample specific classification output
The output from classify and filter can contain fields that are separated by sample and labeled with the sample name. This output is expected when the
flnc_count.txt file from
isoseq collapse is input using
--flnc to classify.
|FL count for the isoform by sample according to the
|Transcripts per million of the FL count for the isoform by sample.
|Log10 of the transcripts per million for the isoform by sample.
|FL count associated with the isoform across all samples in input.
The classify tool outputs a txt file containing every junction for each isoform (
_junctions.txt) following the SQANTI3 junction file convention.
The filter tool outputs a txt file containing the reasons an isoform was filtered.
Reasons an isoform can be filtered:
|The primer was annealing to downstream A-rich regions.
|The isoform contains a single exon.
|There is an artifact of reverse transcriptase template switching.
|There is a low sample coverage for splice sites that are not in the known “canonical” set of splice sites.

The report tools outputs a txt file containing the read count and number of unique genes found in a subsampled number of reads.
The make-seurat tool outputs the required files to run tertiary analysis with Seurat.
