I tried from 3 different linux boxes, but get the same error :

Exception in thread "main" java.lang.NoClassDefFoundError: uk/ac/bbsrc/babraham/FastQC/FastQCApplication
java -Xmx250m -classpath /usr/local/FastQC uk.ac.bbsrc.babraham.FastQC.FastQCApplication
If you have a non-standard classpath on your machine (which you probably won't by default) you may need to append your existing classpath:
java -Xmx250m -classpath /usr/local/FastQC:$CLASSPATH uk.ac.bbsrc.babraham.FastQC.FastQCApplication
Hopefully that should get you up and running.

Thank you Simon, the second command worked. I guess the classpath we have is non-standard!
FastQC works great! Very helpful tool - a great way to get a quick look at the data.

I've just put FastQC v0.2 up on our website. The main changes are:- Some basic colorspace support
- An option to create unzipped reports directly as well as the original zip files
- An option to customise the HTML reports to add your own site branding
- Adding an easily parsed summary file to allow pipelines to quickly flag potential problems
There are also numerous smaller fixes to make things work more smoothly.
You can get the new version from:
http://www.bioinformatics.bbsrc.ac.uk/projects/fastqc/

Some feature requests: could you add ability to
1) read in gzipped FASTQ files
2) be able to reload reports to view again
Thanks for this package - nice and convenient

I can't see why you'd want to do 2 though. If you save a report you get an HTML version which you can open immediately and which shows exactly the same information as you had in the interactive report, or am I missing something?

This is an excellent tool, wish I'd had it months ago!
Any chance you could add functionality for colorspace-based fastq files, produced by the solid2fastq script in BWA? Right now the per base sequence content, per base GC content, per sequence GC content, and per base N content tests aren't working for my reads.

Any chance you could let me have an example file which isn't working? We don't use SOLIDs here so I only have a small set of examples. Contact me off list ([email protected]) if you can help - I should only need a small fragment of the file to be able to figure out why it's not working.

FastQC v0.3 released
I've just put FastQC v0.3 up on our website. This should fix the problems with unrecognised colorspace files and adds back the type of quality score identified into the HTML report files.
There are a couple of new features. The main one is a system for identifying the source of any overrepresented sequences. The program now has a list of all of the primers and adapters commonly in use on sequencing platforms and will scan any overrepresented sequences to see if they match against these. If anyone has any other common sources of contamination they know of they can either add them to their local installation, or preferably pass them back to me so I can add them in to future versions of FastQC.
Another change is a new parameter which can be passed to the non-interactive version of the program to specify a non-default output directory for reports. This should help people who only have read-only access to the original sequence files, but still want to generate reports automatically.
Finally the program now supports the processing of gzip compressed fastq files, since some sites apparently compress their data for long term storage.
You can get the new version from:

I've been using FastQC in interactive mode and it's a really great tool.
I just tried to install and run FastQC v0.3 in non-interactive mode but got this error below (I'm running it on a Mac 10.6).

I'll put out an update which fixes this, but the temporary work round is to go into the Templates directory and do:
rm -r .svn
..which should fix the problem in the current version.
Sorry about that.
Simon.

Dear Simon,
Thank you for the great software! I find the report to be very clear and informative. The docs on how to interpret the report are clear and very helpful. I will probably incorporate FastQC in my pipeline.
I had FastQC test one of my raw reads files. The file is approx. 4.5 GB (FastQC says 21107088 sequences) and all reads are 76 bases. It took FastQC about 5 minutes to process the file (I like the progress report!). Fast enough for me!
One problem did arise:
Code:Failed to process -Dfastqc.output_dir=./fastqc/ :fastqc doesn't exist
Thanks for the hard work,
WilLast edited by Bruins; 05-27-2010, 01:53 AM.

Next-generation sequencing (NGS) and quantitative polymerase chain reaction (qPCR) are essential techniques for investigating the genome, transcriptome, and epigenome. In many cases, choosing the appropriate technique is straightforward, but in others, it can be more challenging to determine the most effective option. A simple distinction is that smaller, more focused projects are typically better suited for qPCR, while larger, more complex datasets benefit from NGS. However,...-

Non-coding RNAs (ncRNAs) do not code for proteins but play important roles in numerous cellular processes including gene silencing, developmental pathways, and more. There are numerous types including microRNA (miRNA), long ncRNA (lncRNA), circular RNA (circRNA), and more. In this article, we discuss innovative ncRNA research and explore recent technological advancements that improve the study of ncRNAs.
