Reference based analysis
1.Filter the raw reads obtained from Illumina Raw Data (paired-ends)according to your desired stringency, to produce a set of high-quality (HQ) sequences in fastq format.
2.Lignment reads (HQ, Fastq format) against Barcode file (Fasta format) using scanAP program.
3.Trim barcodes and filter paired-ends using trim_seq.pl. Classified paired-ends using fltfastq2pe.pl. to produce output “R1.trim.pair.fastq” and “R2.trim.pair.fastq”.
4.The filtered sequence reads were aligned to the reference genome using the Bowtie2, allowing a maximum of four mismatches and one gap of up to 3 bp. Using the SAMtools pileup command the variable positions (SNPs) were determined.
5.AFSM_meth_V_1.0.pl are used for analyses of AFSM methylation results were based on comparisons of assembled sequences .
perl AFSM_meth_V_1.0.pl -i output.sort.bam -o output.meth.matrix

GapFiller
A de novo local assembler for paired reads
SimulaTE
SimulaTE allows to simulate arbitrary complex landscapes of transposable elements (TEs). Additionally reads may be simulated using the genomes of all indivdiuals in the population as template. Reads may be simulated using different sequencing technologies (PacBio, Illumina paired-ends) and strategies (sequencing individuals and pooled populations). SimulaTE will greatly aid in evaluating the suitability of different approaches for estimating TE abundance within populations and to test whether given genomic resources, such as a reference genome or a TE database (a fasta file containing consensus sequences of TEs), are suitable for TE identification.

IMAGE
IMAGE stands for Iterative Mapping and Assembly for Gap Elimination. It is a software designed to close gaps in any draft assembly using Illumina paired end reads.
palfinder
pal_finder is a perl script that finds microsatellite repeat elements directly from raw 454 or Illumina paired-end sequencing reads. It then designs PCR primers to amplify these repeat loci (Potentially Amplifiable Loci: PAL).
GemSIM
GemSIM is a software package for generating realistic simulated next-generation sequencing reads with quality score values. Both Illumina and Roche/454 reads (single or paired end) can be simulated using appropriate empirical error models.
