gatk SplitNCigarReads \
-R /public/home/zjwang/rna-seq/rice_index/all.con \
-I /public/home/zjwang/rna-seq/2018_WH/rna-seq_gatk/star_2pass/allign/YY-1.dedup.bam \
-O /public/home/zjwang/rna-seq/2018_WH/rna-seq_gatk/star_2pass/allign/YY-1.dedup.split.bam \
-RF ReassignOneMappingQuality \

    HI @zjwang

    Can you please post the entire error log and the version of gatk you are using.

    HI @bhanuGandham
    thank you for your answer
    the version of gatk is ''
    the entire error log as follow:
    Using GATK jar /public/home/software/opt/bio/software/GATK/

    USAGE: SplitNCigarReads [arguments]

    A USER ERROR has occurred: Argument '[R, reference]' cannot be specified more than once.

    Set the system property GATK_STACKTRACE_ON_USER_EXCEPTION (--java-options '-DGATK_STACKTRACE_ON_USER_TION=true') to print the stack trace

    I guess it is a version update, the code and parameter have changed now. I hope I can get your advice.

    Maybe you had a typo when you originally ran the command? In your log the input looks pretty peculiar, no? It is missing -o between "bampublic" -I /public/home/zjwang/rna-seq/2018_WH/rna-seq_gatk/star_2pass/allign/YY-1.dedup.bampublic/home/zjwang/rna-seq/2018_WH/rna-seq_gatk/star_2pass/allign/YY-1.dedup.split.bam
