I am a complete newbie in the world of bioinformatics. A molecular biologist by training and working 95% of the time at the bench, I am trying to learn how to download exon sequences that are expressed in all tissues for a list of 200 mouse genes and save them into a single FASTA file. I want to then scan for certain motifs in these sequences in a batch mode by feading the FASTA file into an online program.
So far, I have been trying to use the Entrez.efetch function in Biopython to fetch the infomation for a single gene and then use a loop function to download all the sequences from ncbi. Could some one tell me if I am heading in the right direction and could you help me out as I am stuck and not getting it to work... If not, could you point me to the right direction?
Many thanks in advance.
