Answer

The full explanation

File size limits depend on the type of file you're uploading:

Standard RAW Files:
  • Maximum size: 100 MB
  • Typical size: 5-50 MB
  • Format: TXT or ZIP compressed
  • Processing: Automatic and immediate
Files Exceeding Limits:

If your file is larger than standard limits:

  • BAM/CRAM files: Too large for direct upload - use "WGS to RAW" conversion service
  • Very large VCF files: Use "VCF to RAW" conversion service
  • Imputed files from other services: May need conversion
  • Custom formats: Contact support for assistance
