How to determine the @RG ?

I'm using the following command to add @RG tag:

java -jar picard.jar AddOrReplaceReadGroups I=input.bam O=output.bam RGID=? RGLB=? RGPL=illumina RGPU=? RGSM=?

What should be the @RG tags values for following parameters:

RGID=?

RGLB=?

RGPL=illumina

RGPU=?

RGSM=?

The link for SRA data is :

Thankyou in advance

Iam searching for the exome data for an eye disease "Glaucoma" obtained by next generation sequencing platform but unfortunately  i am not able to get that data. I have already searched ncbi SRC, GEO data sets of ncbi but no data is available. Is there any database other than these to get data in FASTQC format?? Or any article related to glaucoma where information about datasets is available.

thanks

There are many mapping tools, and each one has its own specifications. Once we have two or more tools for similar purposes, how can we say which tool is better?

I am currently dealing with new contig assembly dataset, and bit confused about N50 and L50 stuff ....

Can anyone tell me how to rectify the problem in Sift ? While am running the fasta sequence of my protein of interest its showing error after few minutes and  few times it giving job id but am not getting the result

where can i find a bioinformatics study partner online , to discuss , work toghether in the field 

what does it mean in protein structure as one domain, two domain, three domain and so on ? can anybody help me to know about this ? if there is any link or related article plz do a share.

PS: in relation protein structure

Hello fellow bioinformaticians,

Does anyone know of any German universities providing Masters' in Bioinformatics in English language?(besides FU Berlin)

Thank you in advance!
