question about ICGC_CNSM_VCF files

[glei1103]

Hi, I worked on CNSM VCF files downloaded from ICGC. I know the vcf files provided CN1 and CN2 values, but I notice a small amounts of mutations only have TCNexact values with CN1 and CN2. Such as below,

1	9509999	.	N		.	PASS	END=9575012;STARTINT=[9509999,9510020];ENDINT=[9549973,9575012];CNVLEN=65014;TCNexact=1.13;	TCN:ACN	1:./.
1	72290017	.	N		.	PASS	END=72319888;STARTINT=[72289966,72290068];ENDINT=[72319700,72320076];CNVLEN=29872;TCNexact=1.13;	TCN:ACN	1:./.
1	72319888	.	N		.	PASS	END=72383950;STARTINT=[72319700,72320076];ENDINT=[72383897,72383950];CNVLEN=64063;TCNexact=1.05;	TCN:ACN	1:./.

Do you know how to assign TCNexact value to CN1 and CN2?

Best wishes,
Lei
