Question about picard BuildBamIndex

Greeting all.

Currently, I have been using Picard's built-in library "BuildBamIndex" in order to index my bam files.

I have followed the manual described in Picard sites but I got error message.

Here is my command line that you can easily understand as below.

java -Xmx8g -XX:ParallelGCThreads=8 -jar $picard/BuildBamIndex.jar I=$RealignedBamDir/$output6

I tried different approach to avoid this error message so I used "samtools index" which i think is also same function as Picard BuildBamIndex.

After using samtools, I successfully got my bam index files.

I suppose that there are no major difference between Picard bamindex and samtools bam index.

I am confusing that why only samtools index procedure is working fine?

Below is my error message when run "BuildBamIndex" from Picard.

    Hi there,

    I'm sorry, I don't know what is wrong here. You should ask this on the Picard/samtools mailing list (see the url indicated in the error message), they may be able to help you.

    Hi sclee1,
    it seems to be a bug in the last version of Picard. Can you confirm which version are you using?
    I just have the same problem (and fount your answer by googling the error) with Picard 128 (latest release),
    I have just tried with version 125 and it works fine.
    Good luck!
    p.s: We should report the bug to the Picard team :-)
