I've been trying to convert my .csfasta and .qual files into a .fastq file for the last two days. I've found two different solid2fastq scripts (one from bfast, I don't remember the other one - might be a link from seqanswers). When I look at my .csfasta file, I see the I have 51 nucleotides for each read (they all start with T for the adapter) and there are 50 characters for each read in my .qual file. When I try to trim one base from the .csfasta files, both scripts trim one character from the quality scores too so my .fastq file has one missing quality score and downstream programs don't like this. What should I use for my conversion that would trim one base from .csfasta but not from .qual?

There is no quality for the adapter (it is assumed true), hence you should have one fewer quality score than the color sequence (with adapter). -
I realize that. so there is no way to obtain a fastq file with equal numbers of sequence characters and quality score characters?Comment

i don't mess around with trimming at all and use the solid2fastq script that comes with bfast. which downstream application can't read your fastq?Comment

I'm trying to use FusionMap currentlyComment
-
Why not remove the first "T" away by a simple python/perl script?Comment
-
well, I don't know perl/python that well but i ended up editing a script and got what i needed that way in the last hour. so yay.Comment

ahmetz,did you successfully applied FusionMap on your Solid data? I want to find fusion genes with Solid RNA-seq data, too. And How does FusionMap aligner work, can it built colorspace index? Can you give me email address for more communication? My Email is [email protected],Thank you!Comment

Genomics studies in neuroscience face a special challenge due to the brain’s complexity and scarcity of samples. Mapping changes in cell type and state using conventional next-generation sequencing methods remains challenging. Advances in technologies like single-cell sequencing, spatial transcriptomics, and long-read sequencing have opened the door to deeper studies of the brain and diseases like Alzheimer’s, amyotrophic lateral sclerosis (ALS), and schizophrenia.

Cancer survival rates have significantly increased in the last few decades in the United States, reaching a combined 70% 5-year survival rate by 2021. Behind this number, there are years of research to find new therapies, drug targets, and early detection methods. But there is one core challenge that keeps slowing down these advances, and it’s about drug resistance.
There is no single reason why many patients don’t respond to treatment as expected. Cancer is...07-08-2026, 05:17 AM
