http://www.youtube.com/user/ManchesterBCF/videos?view=1&flow=grid for video tutorials.

.

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.

Answer: A: Method for creating an EMBL formatted annotated sequence?
... 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]. [1]: https://github.com/NBISweden/EMBLmyGFF3 ...

Method for creating an EMBL formatted annotated sequence?
... 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. ...

Answer: A: What shall I do with this RNA-seq data that have no replicates?
... 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. ...

Answer: A: How to repair *all* problems identified by FastQC?
... A good way to solve the errors (taking into account what the other said about their relevance) is to run the reads through a trimming tool, such as Trimmomatic, cutadapt, etc. Not only will poor quality reads/bases be removed, but also adapters. Often rerunning fastqc will show a vast improvement. ...

Answer: A: Biological significance of Fold_enrichment in macs2
... The fold enrichment score compares the read/fragment count at the binding region summit against the local background model. For me it is the second most useful statistic after the qvalue. After sorting by qvalue I sort by fold enrichment. I tend to discount regions with FE < 5, as these tend t ...

Comment: C: How can I locate motif in DNA sequence.
... If you use the UCSC browser you can enable the Public Trackhub 'JASPAR 2018 TFBS', which is good for the following genomes: hg19, hg38, ce10, dm6, sacCer3, and araTha1. You can enter the coordinates of your sites of interest as Custom Tracks, as BED formated genome coordinates. ...
