Exception during loading of vcf.gz file

[ddemaeyer]

Version VCFComp 0.4.0 using Adam 17.1

Loading a gzipped vcf file results in
aG_1: org.apache.spark.rdd.RDD[org.tmoerman.adam.fx.avro.AnnotatedGenotype] = MapPartitionsRDD[2] at filter at :53
htsjdk.tribble.TribbleException: Input stream does not contain a BCF encoded file; BCF magic header info not found, at record 0 with position 0:

Loading the VCF file after unzipping works.

This is probably related with HadoopGenomics/Hadoop-BAM#70
