I'm trying to annotate vcf files for dbNSFP using snpSIFT.
I have downloaded the database and index file from the snpSift manual page.
I'm getting error when i run the program
java -jar ~/snpEff_latest_core/snpEff/SnpSift.jar dbnsfp -v -db ~/snpEff_latest_core/snpEff/0B7Ms5xMSFMYlSTY5dDJjcHVRZ3M.gz comb.vcf > out.vcf

Input file : 'comb.vcf'
Database file : '/home/jannahS/snpEff_latest_core/snpEff/0B7Ms5xMSFMYlSTY5dDJjcHVRZ3M.gz'
Fatal error: Tabix index not found for database '/home/jannahS/snpEff_latest_core/snpEff/0B7Ms5xMSFMYlSTY5dDJjcHVRZ3M.gz'.
SnpSift dbNSFP only works with tabix indexed databases, please create or download index.
Do I need to do something on the index file that I've downloaded?
