AGG Barley - Release 260430

Genotype files for 27,242 barley Plant Genetic Resources from the Australian Grains Genebank genotyped with the Illumina Infinium Wheat Barley 40K v1.1 BeadChip. Genotype data is available in four formats: Tab-delimited text file - unanchored to any genome (260430_AGG-Barley_Raw_unphased_unanchored_genotypes.tsv.gz) Raw comprehensive Variant Call Format (VCF) file - contains all markers, including those anchored to the specified genome, and those that could not be anchored being placed in 'ChrUnk' (eg: 260430_AGG-Barley_MorexV3_Raw_phased_anchored_comprehensive.vcf.gz) Raw unique VCF file - contains only markers that could be anchored to the specified genome, with redundant markers (mapping to duplicated positions) removed (eg: 260430_AGG-Barley_MorexV3_Raw_phased_anchored_unique.vcf.gz) Filled-in unique VCF file - same as the raw unique file, but missing genotype calls have been imputed (eg: 260430_AGG-Barley_MorexV3_Filled_in_phased_anchored_unique.vcf.gz) Users are advised to refer to the README file for more information. Generally, files 3) or 4) are more appropriate for immediate use in downstream bioinformatics tools, while 1) and 2) should be used when a user is interested in analysing the maximum number of markers, regardless of being genome-anchored. Sample information is contained in 260430_AGG-Barley_Biosample_sheet.tsv. Detailed descriptions of each file are included in the README. Funded by the Australian Grains Genebank Strategic Partnership, a $30M joint investment between the Victorian Government and the Grains Research and Development Corporation that aims to unlock the genetic potential of plant genetic resources for the benefit of Australian grain growers.本数据集包含澳大利亚谷物基因库（Australian Grains Genebank）采用Illumina Infinium小麦-大麦40K v1.1芯片完成基因分型的27242份大麦植物遗传资源的基因型文件。 该基因型数据共提供四种格式： 1. 制表符分隔文本文件：包含未分相且未锚定至任何参考基因组的基因型数据（示例文件："260430_AGG-Barley_Raw_unphased_unanchored_genotypes.tsv.gz"）； 2. 原始综合变异调用格式（Variant Call Format，以下简称VCF）文件：包含所有标记，其中既包含锚定至指定参考基因组的已分相标记，也包含无法锚定、被归入"ChrUnk"（未知染色体）的标记（示例文件："260430_AGG-Barley_MorexV3_Raw_phased_anchored_comprehensive.vcf.gz"）； 3. 原始唯一VCF文件：仅包含可锚定至指定参考基因组的已分相标记，已移除映射至重复位点的冗余标记（示例文件："260430_AGG-Barley_MorexV3_Raw_phased_anchored_unique.vcf.gz"）； 4. 填充型唯一VCF文件：与原始唯一文件内容一致，但已对缺失的基因型分型结果进行插补（示例文件："260430_AGG-Barley_MorexV3_Filled_in_phased_anchored_unique.vcf.gz"）。 建议用户参阅README文件以获取更多详细信息。通常而言，第3类或第4类文件更适合直接用于下游生物信息学工具分析；若用户希望最大化分析标记数量、无需考虑标记是否锚定至基因组，则可使用第1类与第2类文件。 样本信息收录于文件"260430_AGG-Barley_Biosample_sheet.tsv"中。各文件的详细说明已包含在README文件内。 本数据集由澳大利亚谷物基因库战略合作伙伴项目资助，该项目由维多利亚州政府与谷物研究与开发公司联合投入3000万澳元，旨在挖掘植物遗传资源的遗传潜力，助力澳大利亚谷物种植者获益。
