I specialise in ChIP-seq analysis, but also run RNA-seq and other NGS applications. Data comes, almost exclusively from illumina sequencers, but I used to mostly analyse SOLiD sequence.
.
I am interested in the analysis, organisation and presentation of genomics data. I have a special place in my heart for the hunting of transcription factor binding sites.

... I have tackled this on a small scale by retaining SAM reads used by htseq-count (--samout), and removing those excluded from the final counts, using sed '/XF:Z:$/d;/XF:Z:__/d'.
After normalisation by DESeq2 I use the scaleFactor to scale the SAM > BAM files, using bedtools genomecov (-scale).

... Thanks to the other contributors, but unfortunately the EMBL format created was not accepted by ENA. However, I have found [EMBLmyGFF3][1], which will create a valid file.
The validation program can be found [HERE][2].
BED to GFF3 used [THIS][3].

... Does anyone have a method for creating an EMBL-flatfile from a FASTA file of sequence, and a BED file of genes and repeats?
The purpose is for submission of an annotate genome to the ENA.
Thanks. ...

... There might still be useful results in experiment 2, but Pvalue and fold change are only indicative at best. The results might give you leads for further lab experiments, or be impressive enough to warrant a second attempt with replication. ...
