FYI, @KARVE, all those manipulation is not needed in the latest release version 1.2.0 of crossbow.

[narain]

@karve, how much are you successful in analysing the output you got ?

[narain]

Okay, I fixed that error. I changed the code TOOLS.PM at relevant point.

[narain]

Here is the command i am using:

$CROSSBOW_HOME/cb_local --input=small.manifest --preprocess --reference=/home/abi/bioinfo/crossbow/crossbow-1.2.0/crossbow-1.2.0/CROSSBOW_REFS/e_coli --output=output_small --all-haploids --cpus=1 --preprocess-output=preprocess_output --keep-all --fastq-dump=/home/abi/bioinfo/sratoolkit/sratoolkit.2.3.1-centos_linux64/bin/fastq-dump

(I tried it for version 1.1.1 as well) .

I get problems with SRAtoolkit, though I do have it in the path specified in the command line. And I have tested my SRAtoolkit to work well.

Similar error in Hadoop - can make it work there

Well, another newbie here, to this stuff at least, but not to IT, so take my suggestions FWIW - on the other hand, I have got it to work all thru the 4 stages so..

I'm using Crossbow 1.1.1 btw.

I tried preprocess in both single machine and Hadoop modes and got this

Bad number of read tokens ; expected 3 or 5:

error in both modes as well. The output ahead and after that message was different for me though:
Mine said:

Written 8909572 spots

From that it was easy to figure out what's happening. In Hadoop mode, for me, the input gut bacteria ( is that right?) file is broken up in 21 files, 18 are legit with data, 2 are empty but still benign, but one file, part_00002 didn't have proper data in it, it had that above text string. So, 20 tasks worked just fine but the one trying to process that part_00002 file failed. So I just deleted that file, edited the shell script to pick up at that point, and voila in hadoop mode it went all the way to the end.

I'm doing everything with keep-all option so the intermediate files are all kept, and I used dry-run mode so that shell-scripts that run things are all kept so I can peek at them and edit them as needed.

Now for me, its on to the next step and to figure out what this all means in the biology aspect :-)

Enjoy.

crossbow error

I got some errors while running crossbow.
I've tried both cb_local and cb_hadoop with example ecoli dataset provided by crossbow.

cmd and parameter:

"cb_local --input=reads --output=out_small --reference=e_coli --all-haploid"

Its giving following error:


Align.pl: Retrived 0 counters from previous stages

Any Suggestion?

Hi Ben
I've installed crossbow on a sun 64 bit server runnng fedora 11 and I'm getting this error
i.e no shellscript was produced
Got any idea what I've done wrong???

Hi Ben,

Sorry to hijack this thread but seeing as you have already answered questions in here I was wondering if it is possible to get bowtie to produce SAM output within the crossbow pipeline. Whenever I pass the '--sam' flag to bowtie using the '--bowtie-args' flag I get a segmentation fault during the align step.

Thanks!

[Michael Robinson]

I found the solutions to the cb_hadoop error
I needed to add to my path the location where I install hadoop

I am running the crossbow using the e_coli data sample

Thanks

[Michael Robinson]

Hi Ben,

I went the NFS route I think is best because I will only need to modify the server with future updates of Crossbow. I can see the Crossbow folders from the client. thanks

I also added to my .profile on the server and the nodes
export $CROSSBOW_HOME=location where I installed Crossbow

Now I have a new challenge. when I run cb_hadoop --test i get "program not found"

I can see cb_hadoop and I can also do a cat on it and read the code.

Crossbow 1.1.0 with Hadoop 0.20.2 Help

Hi Ben,

I am impressed how fast you replied.

Thanks very much

Michael

[Ben Langmead]

Hi Michael,

I have Hadoop 0.20.2 running on a multi-node cluster, one server two nodes

Following Crossbow 1.1.0 installation instructions in the manual, I installed it in the server and tested it. no problems.
Now I want to install it (Bowtie and SOAPsnp) in the nodes following the same instructions:

"If you plan to run on a Hadoop cluster, you may need to manually copy the bowtie and soapsnp files to the same path on each of your Hadoop cluster nodes. You can avoid this step by installing bowtie and soapsnp on a filesystem shared by all Hadoop nodes (e.g. an NFS share). You can also skip this step if Hadoop is installed in pseudo distributed mode, meaning that the cluster really consists of one node whose CPUs are treated as distinct slaves."

Could you please tell me: when you say "copy the bowtie and soapsnp files to the same path on each of your Hadoop cluster nodes." how are they related to the server install, do you mean an exact path as the Crossbow path in the server?

Yes, it's best to install 'bowtie' and 'soapsnp' at the same path on all nodes, including the server. It's not strictly necessary to install those tools on the server at all, but if you don't the "cb_hadoop --test" command will fail when run from the server.

Could you give an example of "You can avoid this step by installing bowtie and soapsnp on a filesystem shared by all Hadoop nodes (e.g. an NFS share)."

All I really mean is that you can set up an NFS share so that all computers in the cluster "see" the same files in certain directories. E.g. you might set up your cluster so that the '/share/crossbow' directory contains a Crossbow install and is NFS-shared across all nodes in the cluster. If you do so, the path '/share/crossbow/bin/linux64/bowtie', for example, will be present on all nodes and you can specify that path using the --bowtie option.

Also, testing previous Crossbow versions I needed to install other programs such as R, bioconductor, samtools, etc, are those programs not needed anymore?

You don't need samtools, no. You never needed R/Bioconductor for Crossbow - just for Myrna (a different though similar tool).

Hope this helps,
Ben

Hi Michael,

Following the Crossbow manual I run cb_hadoop getting:

michael@HOST:~/crossbow_1.0.4/crossbow-1.0.4$ cb_hadoop
Must specify -reference

then I run:

cb_hadoop.pl -reference=$CROSSBOW_REFS/e_coli.jar

which is the location of the jar files for e_coli, then I got this error:

-------------------

You'll have to specify input and output directories using --input and --output as well. Depending on your version of Hadoop and how it's set up, you may need to specify HDFS URLs that include your namenode's address and port; e.g.: -input= hdfs://localhost:9000/my/input.

Hope this helps,
Ben

Thank very much for your help.

I downloaded version 1.0.4, installed it and all corresponding programs, run it in a single computer using e_coli, and everything worked fine. Then I created a Virtual Machine (ubuntu) and repeated the same step with the same results.

Now I am trying to run the same job using Hadoop (cb_hadoop), but I think I am missing at least one step.

Following the Crossbow manual I run cb_hadoop getting:

michael@HOST:~/crossbow_1.0.4/crossbow-1.0.4$ cb_hadoop
Must specify -reference

then I run:

cb_hadoop.pl -reference=$CROSSBOW_REFS/e_coli.jar

which is the location of the jar files for e_coli, then I got this error:
