PseudoChecker  consists in an integrated computational pipeline able to infer the coding status of a given eukaryotic nuclear protein-coding gene in single or multiple species of interest by taking advantage of existent genomic data.

Biological data input

Genomic sequence per target species:

(Genomic scaffold, genomic contig, genomic sequencing read - FASTA format)

Coding exons and CDS of the reference species' in-study candidate gene:

(Exons should be inserted from the 5' to the 3' end of the gene - FASTA format)

Basic Options - Coding sequence prediction parameters

Similarity scoring scheme:

(Match: 1; Mismatch: -3; Gap opening: -8; Gap extension: -1)

(Match: 1; Mismatch: -1; Gap opening: -8; Gap extension: -1)

Automatically chooses the similarity scoring scheme most adequate to each exon alignment

UTR trimming:

Extension of the reference species' 3' exon alignment to find a missing (in the original alignment) downstream final stop codon:

Minimum exon alignment identity (%):

Minimum alignment identity between the reference species' coding exon and target species' genomic sequence to be considered as a valid alignment (30% minimum).

Advanced options

MACSE alignment costs:

Reliable sequences:

Frameshift cost  Cost of an internal frameshift (those between the first and last codon)  

Terminal frameshift cost  Cost of a terminal frameshift (those in the first and last codon)  

STOP codon cost  Cost of a stop codon arising from the first to the penultimate codon  

Less reliable sequences:

Frameshift cost  Cost of an internal frameshift (those between the first and last codon)  

Terminal frameshift cost  Cost of a terminal frameshift (those in the first and last codon)  

STOP codon cost  Cost of a stop codon arising from the first to the penultimate codon  

Common costs:

Gap opening  Cost of internal gap opening (those between the first and last codon)  

Gap extension  Cost of internal gap extension (between the first and last codon)  

Terminal gap opening  Cost of terminal gap op. (before the first nt and after the last one) 

Terminal gap extension  Cost of terminal gap ext. (before the first nt and after the last one) 

Predetermined coding sequences:

(Optional - FASTA format)
