some problem with tophat
 

has anyone here used tophat ?
when i map single-end solid sequences(fastq format) to hg18 as follow:
~/bin/tophat bowtie-0.11.3_index/hg18 query.fq -o mapre -a 5 -m 2 -i 70 -I 5000 --solexa1.3-quals -g 40 -p 4

there is such error:
Error: you must set the mean inner distance between mates with -r
Traceback (most recent call last):
File "/picb/home55/zsli/Public/mapping/bin/tophat", line 1487, in ?
sys.exit(main())
File "/picb/home55/zsli/Public/mapping/bin/tophat", line 1402, in main
exit(1)
TypeError: 'str' object is not callable

what's going on ?
can anyone help me? thanks in advance~~

Wrong forum
 

removed...I was in the wrong forum

In the command above, you are placing the arguments (the index name and the FASTQ file of your reads) before the options. It should be:

tophat -o mapre -a 5 -m 2 -i 70 -I 5000 --solexa1.3-quals -g 40 -p 4 bowtie-0.11.3_index/hg18 query.fq

yes, that works, thanks a lot !

Similiar sort of problem.
 

Hi all,

I am getting this error

while running tophat

tophat -r 200 -i 50 -I 250000 /home/deepak/bowtie-0.12.5/indexes/hs_genome 37_NoIndex_L001_R1_001.fastq -o tophat_new &

Please help me with this error.

Thanking you in advance.

maybe try the last version of tophat 1.4.1

Aside from using a newer version, you might try "tophat -o tophat_new -r 200 -i 50 -I 250000 /home/deepak/bowtie-0.12.5/indexes/hs_genome 37_NoIndex_L001_R1_001.fastq" instead. Depending on how tophat parses how it's called, what you wrote as a command could cause an issue (the error suggests that it's trying to open a file called "-o", suggesting that it's not seeing that as an option but a file name).
