Data frames of allele counts at variant positions per cell. Variant positions can be either common single nucleotide polymorphisms (SNPs) positions or individual-specific heterozygous positions retrieved by bulk sequencing.
Format
A data frame with columns based on the Variant Call Format (VCF) columns. It contains the following columns:
cell
Barcodes of cells (
character
).id
Variant unique identifier defined as CHROM_POS_REF_ALT, e.g. "1_920949_C_G" (
character
).CHROM
Chromosome in integer format, e.g. 15 (X and Y chromosomes are not included) (
integer
).POS
Position of the variant (1-base positions) (
integer
).REF
Reference allele base, "A" "C" "G" or "T" (
character
).ALT
Alternative allele base, "A" "C" "G" or "T" (
character
).RD
Reference allele depth/count (
integer
).AD
Alternative allele depth/count (
integer
).DP
Total depth/count (
integer
).GT
Genotype: "0/1" or "1/0" if unphased; "0|1" or "1|0" if phased. (
character
).
