"Java.lang.AssertionError:SAM dictionaries is not the same" error while running the program

Java-jar Picard.jar sortvcf     i=1000g_phase1.indels.hg19.sites.vcf     o=1000g_ PHASE1.INDELS.HG19.SITES.SORTED.VCF     sequence_dictionary=hg19.dict

Note To update hg19.dict first, run the following command before you go ahead:

Java-jar Picard.jar updatevcfsequencedictionary     i=1000g_phase1.indels.hg19.sites.vcf     O=1000G_ PHASE1.INDELS.HG19.SITES.DIC.VCF     sequence_dictionary=hg19.dict

After running, you will get the 1000G_PHASE1.INDELS.HG19.SITES.DIC.VCF file

Then enter the following command:

Java-xmx60g-jar Picard.jar sortvcf     i=1000g_phase1.indels.hg19.sites.dic.vcf    o=1000g_ PHASE1.INDELS.HG19.SITES.SORTED.VCF     sequence_dictionary=hg19.dict
