Hi,

I decided to use HOMER in order to find known motifs in a file. My file is in BED format. Since I have BED files and .pos files, I decided to use findMotifGenome.pl and I call it as it is in the manual. I got this output where I have empty output file. After I checked the possible problems; even though bed2pos.pl, checkPeakFile.pl cleanUpPeak.pl etc are located in the bin file, they cannot be located thus I got this error. I got the same results with giving either BED/.pos file. Could you help me out with this?

Best regards,

I wish you all a good new year.

It seems you didn't install HOMER correctly, as there are many "command not found" errors.

well I followed the instructions as it is written in the guide. http://homer.salk.edu/homer/introduction/install.html. The instillation is consisted of one line code. Also, I have used one of the functions before and then got the same output with the reinstalled one??

Why don't you use the MEME suite? This set of tools specialises on motif discovery. You can install it or run it online.

To avoid this error, add the homer/bin directory to your executable path(~/.bash_profile file).

two steps:

(1) vim ~/.bash_profile
(add a line)
(2) source ~/.bash_profile

you can check install instruction in official url [Installing the basic HOMER software]
