BOL

In school the teachers refer to both terms as one, but according to what I have read they are not the same and don't use the same methologies so I am a bit confused.

I used the following command to print the blast hit.

[Terminal] blastn -query aaa.fa -db blastdb/nt -evalue 10e-5 -num_threads 4 -max_target_seqs 1 -outfmt '6 qseqid staxid qstart qend sallseqi sstart send evalue length frames qcovs' -out testBlastSee

But the outfile print many hits, I only want the top one.

[Terminal] more testBlastSee                                                                                                                  []

I am looking for new, interactive and user friendly tools to see chromosomal rearrangements. I tried IGV, but it does not seems to be very helpful for chromosomal rearrangements visualization. Circos look pretty useless, as it does not allow me to explore well. Help Please...

I want to publish my research work on miRNA. I used online "freely" available miRNA dataset, with not known publications, and analysed it. Can you please suggest your experience publishing it in a good Impact Factor Journal? Is this possible to published it?

If i have a set of miRNA sequences, what are the tools that are available to predict the target genes? I tried miRanda and mirdb, are there any  tools or databases that do the same, as the rna is not already known i cant use targetscan etc. The tool must predict the target from the fasta sequence of miRNA.

Thank you
