NAME¶

ecoPCR - searching for sequence and taxonomy hybriding with given primers

SYNOPSIS¶

ecoPCR [options] <nucleotidic patterns>

DESCRIPTION¶

ecoPCR is an electronic PCR software developed by LECA and Helix-Project. It helps to estimate Barcode primers quality.

OPTIONS¶

-a : Salt concentration in M for Tm computation (default 0.05 M)

-c : Consider that the database sequences are [c]ircular

-d : [D]atabase : to match the expected format, the database

has to be formatted first by the ecoPCRFormat(1) program. ecoPCRFormat(1) creates three file types:

.sdx : contains the sequences

.tdx : contains information concerning the taxonomy

.rdx : contains the taxonomy rank

ecoPCR needs all the file type. As a result, you have to write the database radical without any extension. For example /ecoPCRDB/gbmam

-D : Keeps the specified number of nucleotides on each side of the in silico

amplified sequences (including the amplified DNA fragment plus the two target sequences of the primers).

-e : [E]rror : max errors allowed by oligonucleotide (0 by default)

-h : [H]elp - print <this> help

-i : [I]gnore the given taxonomy id.

Taxonomy id are available using the ecofind program. see its help typing ecofind -h for more information.

-k : [K]ingdom mode : set the kingdom mode

super kingdom mode by default.

-l : minimum [L]ength : define the minimum amplication length.

-L : maximum [L]ength : define the maximum amplicationlength.

-m : Salt correction method for Tm computation (SANTALUCIA : 1

or OWCZARZY:2, default=1)

-r : [R]estricts the search to the given taxonomic id.

Taxonomy id are available using the ecofind program. see its help typing ecofind -h for more information.

first argument : oligonucleotide for direct strand

second argument : oligonucleotide for reverse strand
