Hi again,
I became really interested in MapView; but unfortunately there are a few things making the output hard to trust.
For example: I have a bad reference strain (bad means that there are ambiguous bases 'N' or 'S' in it). Then MapView produces an odd output for the reference. I have attached two cut screen shots. One is from MapView and one is from the NCBI viewer. Both have the same reference sequence.
When you look at the MapView output, you see that on position 71275 and 71277 are ambiguous bases. Now look on the position after these two (71276, 71278 and 71279) .. you will see three 'T's and only one of the is true. You can easily compare it with the NCBI view. The marker is positioned on 71275. Position 71276 is a 'G', 71278 is a 'T' (this one is correct) and 71279 is a 'C'.
Any suggestions why this happens?

In this way I could compare my annotation shown in a GenomeBrowser with the mapping of my exon reads on the reference.
Many thanks
Of course, the killer feature would to be able to visualize the various annotation tracks on GenomeBroswer from within MapView along with the reads. I've seen a few commercial programs that do this, but even they were still a bit clunky.

Yes .. that's the way I do it now.
But I am looking for something to do it simultaneously. I have attached a screenshot where I have put two views horizontal. Now it would be nice, to have these two screens position-wise exactly one above the other. And one scroll bar between them to scroll at the same time through both alignments.Attached Files

I am doing a lot of comparisons and therefore I am jumping between two views a lot.
So for my analysis it would be useful to load e.g. two different MVR files into the program with a split screen and to scroll through both screens at the same time.
I don't know how complicated it could be to add or even how useful it could be for other people, but maybe this is something you would be interested in?
Thanks!
At present, you can run many MapViews and load many MVF files.
In one MapView, you can open many SNP Lists.

I'm using HyperSnap (screen capture program) for that. It has text capture mode, can get text from scrolling windows and output it in tab-delimited format. I guess SnagIt also might do something like that. Unfortunately, both these software pieces are commercial.Originally posted by Drake View PostThanks for your answers ..
It's a pity that there is no simple button to export this region ... so I will stay with my MAQ flat files in cyqwin ...
It has the simple button now. ^_^Last edited by WJW-Davy; 05-01-2009, 07:49 PM.

MapView 3.1.4 The SNP list can be exported to a flat file.
Download Link : https://sites.google.com/site/wjwdavy/
[Change Log - main versions]
3.1.4 [2009.5.2]
Text can be copyed from SNP list.
MVR file can be converted to text file. The SNP list can be exported to a flat file.
3.0 [2009.3.8]
Significant improvement.
Quality Score, Paired-end data, structure variation, coverage distribution, quality distribution, text quick view, zoom in/out, and other features are supported.
2.0 [2008.12.16]
Significant improvement.
Support many formats. Fasta format and text-based alignment results file(output by Eland, Maq, SOAP, MapNext, SeqMap … …).
1.0 [2008.11.28]
This is the first attempt.
Only support MapNext's formatLast edited by WJW-Davy; 05-05-2009, 04:43 AM.

Hello,
is there a way to export the SNP list to a flat file? Like the one maq produces?
Thanks!

The new version is being planned. We are discussing the new features.
SAM/BAM format will be supported.
A command line version will be available.
... ...

The sequencing world is rapidly changing due to declining costs, enhanced accuracies, and the advent of newer, cutting-edge instruments. Equally important to these developments are improvements in sequencing analysis, a process that converts vast amounts of raw data into a comprehensible and meaningful form. This complex task requires expertise and the right analysis tools. In this article, we highlight the progress and innovation in sequencing analysis by reviewing several of the...-

The field of epigenetics has traditionally concentrated more on DNA and how changes like methylation and phosphorylation of histones impact gene expression and regulation. However, our increased understanding of RNA modifications and their importance in cellular processes has led to a rise in epitranscriptomics research. “Epitranscriptomics brings together the concepts of epigenetics and gene expression,” explained Adrien Leger, PhD, Principal Research Scientist...-
