Online imputation

Step 1:Data input

Current species : {{edit.Name}}

Users can upload one or more vcf.gz files. The input files must be named ${chromosome_name}.vcf.gz, for example: {{vm.edit.speciesVcfName}}. Please check the list of chromosomes. Please note, users can upload a file with a maximum size of 50MB. Datasets larger than that should be uploaded via FTP or analyzed locally using the standalone package.

Please upload the vcf file:
