Error details: SAM file doesn't have any read groups defined in the header. The GATK no longer supports SAM files without read groups
##### ERROR ------------------------------------------------------------------------------------------
This is the error message that i received. i have tried AddOrReplaceReadGroups and FixMateInformation and ReplaceSamHeader and ValidateSamFile from which i got an ERROR :Missing_Read_Groups.
i am very new to programming and bioinformatics,
i am using this syntax for HAPLOTYPECALLER:
java -jar /home/mahnoor/Documents/SOFTWARES/GATK_MINE/GenomeAnalysisTK.jar -T HaplotypeCaller -R /home/mahnoor/Documents/IGV_DATA/Wheat_DATA/test_wheat/test_data/reference.fa -I /home/mahnoor/Documents/IGV_DATA/Wheat_DATA/reference.bam -o /home/mahnoor/Documents/IGV_DATA/Wheat_DATA/reference.bam.vcf
as you can see i have given all my files the same name in case the system is not recognizing the file.
Can you please let me know what im doing wrong or what else can i do? any help would be much appreciated.
Thank you.
The error is really self-explanatory and googling the error message would tell you what you need.
Error details: SAM file doesn't have any read groups defined in the header.
You need Picard AddOrReplaceReadGroups.
i am very new to programming and bioinformatics,
SPOILER ALERT: you will spend the next few months/years googling error messages and hopping from error to error until something works. Welcome to bioinformatics. But it will get better.
alright ! thanks But i have tried picards AddOrReplaceReadGroups twice, it still gives the same error?
Hello,
what was the exact command you use for Picards AddOrReplaceReadGroups? Please also post the bam header. For this you can use this command:
samtools view -H /home/mahnoor/Documents/IGV_DATA/Wheat_DATA/reference.bam
fin swimmer
The exact command for Picards AddOrReplaceReadGroups which i used: java -jar picard.jar AddOrReplaceReadGroups -I reference.bam -O reference.rg.bam RGID=s_6 RGPL=illumina RGPU=HWUSI-EAS535_0025 RGSM=s_6
i used your command, this is what i got
samtools view -H /home/mahnoor/Documents/IGV_DATA/Wheat_DATA/reference.bam
@SQ SN:T_aestivum_b59 LN:14738 @PG ID:bwa PN:bwa VN:0.6.0-r85
You need to continue with the reference.rg.bam. Not the reference.bam.
i changed the previous command a little, i have used this instead
java -jar picard.jar AddOrReplaceReadGroups I=/home/mahnoor/Documents/IGV_DATA/Wheat_DATA/reference.rg.bam O=/home/mahnoor/Documents/IGV_DATA/Wheat_DATA/referenceoutput.rg.bam RGID=4 RGLB=lib1 RGPL=illumina RGPU=unit1 RGSM=20
this is what im getting

Which command did you use with GATK this time?
java -jar /home/mahnoor/Documents/SOFTWARES/GATK_MINE/GenomeAnalysisTK.jar -T HaplotypeCaller -R /home/mahnoor/Documents/IGV_DATA/Wheat_DATA/test_wheat/test_data/reference.fa -I /home/mahnoor/Documents/IGV_DATA/Wheat_DATA/reference.bam -o /home/mahnoor/Documents/IGV_DATA/Wheat_DATA/reference.bam.vcf
^ using this command
You need to continue with the reference.rg.bam. Not the reference.bam.
java -jar /home/mahnoor/Documents/SOFTWARES/GATK_MINE/GenomeAnalysisTK.jar -T HaplotypeCaller -R /home/mahnoor/Documents/IGV_DATA/Wheat_DATA/test_wheat/test_data/reference.fa -I /home/mahnoor/Documents/IGV_DATA/Wheat_DATA/reference.rg.bam -o /home/mahnoor/Documents/IGV_DATA/Wheat_DATA/reference.bam.vcf
^ This is what i command with reference.rg.bam
but it gives an error-- *##### ERROR MESSAGE: Could not read file /home/mahnoor/Documents/IGV_DATA/Wheat_DATA/reference.rg.bam because java.io.FileNotFoundException: /home/mahnoor/Documents/IGV_DATA/Wheat_DATA/reference.rg.bam (No such file or directory)
<h5>ERROR ------------------------------------------------------------------------------------------*</h5>
This means the path to reference.rg.bam is incorrect. GATK has very clear error messages most of the time, you just have to read them.
Based on your previous command the path should be /home/mahnoor/Documents/IGV_DATA/Wheat_DATA/referenceoutput.rg.bam I believe, but these are issues you should be able to solve yourself.
IT WORKED! I WAS USING THE PREVIOUS PATH. i continue with the new one and it worked!Thank you!
