I am using the following command:
findMotifs.pl input.fa fasta ./Output -fastaBg bg.fa -len 8,10,12 -norevopp
The input and bg fasta have this structure and the bg fasta include all sequences in input plus many others:
>ENSMUST00000027125_Coq10b_mmu_chr1_55071635_55072702_+_utr_55071803_55072702(+)
However I get the following error:
Selected Options:
Input file = input.fa
Promoter Set = fasta
Output Directory = ./CPEB4
Will use FASTA files for motif finding
Target Sequences = input.fa
Background Sequences = bg.fa
Motif length set at 8, 10, 12,
Will not search the reverse strand
