Aspergillus fumigatus Datasets
|
|
| JCVI 2011 |
| | Source: Data supplied to AspGD by Natalie Fedorova, JCVI. This project has been funded in whole or part with federal funds from the National Institute of Allergy and Infectious Diseases, National Institutes of Health, Department of Health and Human Services under contract numbers N01-AI30071 and / or HHSN272200900007C. |
| | Notes: A. fumigatus isolates: 4 "reference" and 19 "target" Aspergillus fumigatus strains have been sequenced using the Illumina platform. The list of sequenced strains includes (i) 7 drug resistant isolates, selected to facilitate the identification of new mechanisms of antifungal drug resistance (F series); (ii) 12 genotypically linked isolates from 2 hospital outbreaks, included to validate the discriminatory power of existing genotyping markers (B series).
SRA submission and metadata can be found here:
It was observed that the sequences of some B-series strains are virtually identical.
For SNP analysis, the following parameters were used:
samtools mpileup -E -ugf AF293.fa F18454.bam | bcftools view -bvcg - > var.raw.bcf bcftools view var.raw.bcf | vcfutils.pl varFilter -D 500 > var.flt.vcf
This reference file used in the alignments (also available for download from link below, AF293_REF.fasta) is the same sequence that was submitted to GenBank:
http://www.ncbi.nlm.nih.gov/nuccore/AAHF00000000
WGS AAHF01000001-AAHF01000019
WGS_SCAFLD CM000169-CM000176
http://www.ncbi.nlm.nih.gov/Traces/wgs/?val=AAHF01
plus the mitochondrial and ribosomal scaffolds, which will be submitted by JCVI later in 2011.
To remove false positives, the VCFs were further filtered using the following parameters:
- Per-site SNP quality (QUAL) >= 70 (default > 50)
- Raw read depth: DP >= 20 (default > 15)
- High quality read depth (DP4): high-quality ref-forward = 0, ref-reverse = 0, alt-forward > 4 and alt-reverse > 4
- Max-likelihood estimate of the first ALT allele count (AC1) = 2
- Max-likelihood estimate of the first ALT allele frequency (AF1) = 1
The parameters were optimized to minimize the number of false positives by analyzing VCF file for AF293 Illumina reads mapped to the current (Sanger AF293) assembly.
The GFF files corresponding to each VCF file were generated at AspGD by converting formats
and mapping scaffolds to chromosomes. |

Aspergillus oryzae Datasets

|
| Wang et al., 2010 |
| | Source: A. oryzae RNA-Seq was performed by Wang B, Guo G, Wang C, Lin Y, Wang X, Zhao M, Guo Y, He M, Zhang Y, and Pan L, at the School of Bioscience and Bioengineering, South China University of Technology, Guangzhou, Guangdong, China. Data were downloaded from NCBI by AspGD. |
| Notes: This A. oryzae RNA-Seq dataset is published in:
Wang B, et al. 2010.
Data were downloaded from NCBI:
http://www.ncbi.nlm.nih.gov/sra?term=SRP001894
This publicly available A. oryzae RNA-Seq dataset comprises eight experiments. Paired-end RNA-sequencing (RNA-Seq), using the Illumina platform, was conducted on polyadenylated-enriched mRNA isolated from four different culture conditions. |
