Hello everyone,
I'm trying to run tuxedo pipeline on ubuntu. But I need to use color command to get the results (I am not sure if it is correct way to analyze SOLID data). Common usage: tophat --color --quals [other options]* <colorspace_index_base> <reads1_1[,...,readsN_1]> [reads1_2,...readsN_2] <quals1_1[,...,qualsN_1]> [quals1_2,...qualsN_2]
I know that but here is my problem; I do not know how to find colorspace_index_base or is there a way for change the solid fastq to illumina fastq.
Thanks.
Did you download the index or did you make it yourself? If you've done neither, then you need to use
bowtie-build
.I search and I did not find now I'm doing bowtie-build ( bowtie-build -C SRR121576.fastq SRR121576)
Ah, you can go ahead and stop that command, it's not what you want. You'll need to either download an index from iGenomes (I assume the files include colorspace indices, but I don't know that for sure), or download the reference genome from UCSC/Ensembl/etc. and use bowtie-build with that.
Since you're very new to this, I'd recommend trying to find someone locally to help you out a bit (that'll get you finished with your analysis a bit more quickly). Alternatively, try to find a course that goes through some of the basics. I know there are some offered in Germany by ecSeq, and I presume there's something similar in Turkey.
I understand you thank you for help :)
Devon, Can you write me the reasons of "Error running 'prep_reads' terminate called after throwing an instance of 'int' " I already download hg 18 colorspace from Bowtie web site and
I fastq-dump some solid SRR (rna-seq) and "tophat -C -o output --bowtie1 colorindex SRR.fastq
And do you see any thing wrong in this code? because it still gives the error
It's unclear. Perhaps post a couple lines for the SRR.fastq file. Hopefully someone more versed in colorspace will see this, since I pretty much never use colorspace datasets (they're pretty antiquated these days).
thanks for everything. Is there any pipeline that I can use analyzing SOLID data that you suggest?
That's unfortunately not something I have enough experience with to offer any advice. Tophat should work, but if it's not then finding out why may not be trivial unless you can code.
Hello Devon I need to ask another question to you ;
Let me write log and command after I'll add my files first lines
This is my fastq file;
Do you see any problem?
Those aren't colorspace reads, I wonder if they tried converting them to base-space (a bad idea) before uploading.
Ok I understand that, thank you :)
