Use '-nf 0' to turn off masking -na --noALN do not output ALN alignment file -o --out the prefix of output filename -p --paired indicate a paired-end read simulation or to generate reads from both ends of amplicons NOTE: art will automatically switch to a mate-pair simulation if the given mean fragment size >= 2000 -q --quiet turn off end of run summary -qL --minQ the minimum base quality score -qU --maxQ the maxiumum base quality score -qs --qShift the amount to shift every first-read quality score by -qs2 --qShift2 the amount to shift every second-read quality score by NOTE: For -qs/-qs2 option,a positive number will shift up quality scores (the max is 93) that reduce substitution sequencing errors and a negative number will shift down quality scores that increase sequencing errors. If shifting scores by x,the error rate will be 1/(10^(x/10)) of the default profile. -rs --rndSeed the seed for random number generator (default: system time in second) NOTE: using a fixed seed to generate two identical datasets from different runs -s --sdev the standard deviation of DNA/RNA fragment size for paired-end simulations. -sam --samout indicate to generate SAM alignment file -sp --sepProf indicate to use separate quality profiles for different bases (ATGC) -ss --seqSys The name of Illumina sequencing system of the built-in profile used for simulation NOTE: sequencing system ID names are: GA1 - GenomeAnalyzer I (36bp,44bp),GA2 - GenomeAnalyzer II (50bp,75bp) HS10 - HiSeq 1000 (100bp),HS20 - HiSeq 2000 (100bp),HS25 - HiSeq 2500 (125bp,150bp) HS10 - HiSeq 1000 (100bp),150bp) HSXn - HiSeqX PCR free (150bp),HSXt - HiSeqX TruSeq (150bp),MinS - MiniSeq TruSeq (50bp) MSv1 - MiSeq v1 (250bp),MSv3 - MiSeq v3 (250bp),NS50 - NextSeq500 v2 (75bp) ===== NOTES ===== * ART by default selects a built-in quality score profile according to the read length specified for the run. * For single-end simulation,ART requires input sequence file,outputfile prefix,read length,and read count/fold coverage. * For paired-end simulation (except for amplicon sequencing),ART also requires the parameter values of the mean and standard deviation of DNA/RNA fragment lengths ===== EXAMPLES ===== 1) single-end read simulation art_illumina -ss HS25 -sam -i reference.fa -l 150 -f 10 -o single_dat 2) paired-end read simulation art_illumina -ss HS25 -sam -i reference.fa -p -l 150 -f 20 -m 200 -s 10 -o paired_dat 3) mate-pair read simulation art_illumina -ss HS10 -sam -i reference.fa -mp -l 100 -f 20 -m 2500 -s 50 -o matepair_dat 4) amplicon sequencing simulation with 5' end single-end reads art_illumina -ss GA2 -amp -sam -na -i amp_reference.fa -l 50 -f 10 -o amplicon_5end_dat 5) amplicon sequencing simulation with paired-end reads art_illumina -ss GA2 -amp -p -sam -na -i amp_reference.fa -l 50 -f 10 -o amplicon_pair_dat 6) amplicon sequencing simulation with matepair reads art_illumina -ss MSv1 -amp -mp -sam -na -i amp_reference.fa -l 150 -f 10 -o amplicon_mate_dat 7) generate an extra SAM file with zero-sequencing errors for a paired-end read simulation art_illumina -ss HSXn -ef -i reference.fa -p -l 150 -f 20 -m 200 -s 10 -o paired_twosam_dat 8) reduce the substitution error rate to one 10th of the default profile art_illumina -i reference.fa -qs 10 -qs2 10 -l 50 -f 10 -p -m 500 -s 10 -sam -o reduce_error 9) turn off the masking of genomic regions with unknown nucleotides 'N' art_illumina -ss HS20 -nf 0 -sam -i reference.fa -p -l 100 -f 20 -m 200 -s 10 -o paired_nomask 10) masking genomic regions with >=5 'N's within the read length 50 art_illumina -ss HSXt -nf 5 -sam -i reference.fa -p -l 150 -f 20 -m 200 -s 10 -o paired_maskN5 (编辑:淮安站长网) 【声明】本站内容均来自网络,其相关言论仅代表作者个人观点,不代表本站立场。若无意侵犯到您的权利,请及时与联系站长删除相关内容! |
