Hi,

Please can anyone help me?

I want to recreate reference.dict (because I deleted the first file) with this command:

java -jar CreateSequenceDictionary.jar REFERENCE=hg19.fa OUTPUT=hg19.dict

But I have this

[Mon May 19 12:49:23 CET 2014] net.sf.picard.sam.CreateSequenceDictionary REFERENCE=hg19.fa OUTPUT=hg19.dict    TRUNCATE_NAMES_AT_WHITESPACE=true NUM_SEQUENCES=2147483647 VERBOSITY=INFO QUIET=false VALIDATION_STRINGENCY=STRICT COMPRESSION_LEVEL=5 MAX_RECORDS_IN_RAM=500000 CREATE_INDEX=false CREATE_MD5_FILE=false
