MosaikAligner: Low reads/sec
I recently decided on using the Mosaik tools as they support Sanger-sequenced data. However, when I run MosaikAligner on a relatively small query set (1.9MB with 1000 sequences) on a cluster with 48 cores, I have a problem with the number of reads per second processed. When MosaikAligner starts out, I have a read rate of 15 reads/sec but this number continuously drops to below .1 reads/sec at which rate even such a small subset of my reads will take over an hour to align. I tested the aligner first using only a 10 sequence query file from the same data set and the alignment was almost instantaneous. Has anyone else used the Mosaik tools and experienced similar problems?

I should mention I'm using these parameters:
-bw 51 -hs 15 -m all -p 48 -mmp .2 -dh
and using a jump database for the reference genome. -
I want to use Mosaik API but when i execute make command in c++ or perl it give error like MosaikAlignment.h:441: error: ‘uint64_t’ does not name a type
MosaikAlignment.h:442: error: ‘uint64_t’ does not name a type
MosaikAlignment.h:444: error: ‘uint64_t’ does not name a type
MosaikAlignment.h:495: error: ‘uint64_t’ does not name a type
MosaikAlignment.h:497: error: ‘uint64_t’ does not name a type
MosaikAlignment.h:527: error: ‘uint64_t’ does not name a type
MosaikAlignment.h:528: error: ‘uint64_t’ does not name a type
MosaikAlignment.h:579: error: ‘uint64_t’ does not name a type
MosaikAlignment.h:582: error: ‘uint64_t’ does not name a type
MosaikAlignment.h:584: error: ‘uint64_t’ does not name a type
MosaikAlignment.h:585: error: ‘uint64_t’ does not name a type
make: *** [MosaikConversionMain.o] Error 1
so any body can help me how i can use API for c++ or perl.Comment

shahid.manzoor, you should start a new thread with your question instead of adding to threads regarding other topics...
Anyway, back to bre's question. I have the exact same problem. I have Illumina 76-mers from exome-capture experments and aligning 1M reads to chr 21 of hg19 using the parameters
on my 8-core, 108Gb machine. The alignment is roughly 15reads/sec initally but slowly falling to <1 read/sec. I'm not using a jump database for this.Code:-mm 12 -act 35 -p 6 -bw 29
Anyone else seen and/or solved this?
Thanks

Ultimately I decided Mosaik wasn't suited to my needs so unfortunately I can't give you a solution...Comment

During the COVID-19 pandemic, scientists observed that while some individuals experienced severe illness when infected with SARS-CoV-2, others were barely affected. These disparities left researchers and clinicians wondering what causes the wide variations in response to viral infections and what role genetics plays.

The first FDA-approved CRISPR-based therapy marked the transition of therapeutic gene editing from a dream to reality1. CRISPR technologies have streamlined gene editing, and CRISPR screens have become an important approach for identifying genes involved in disease processes2. This technique introduces targeted mutations across numerous genes, enabling large-scale identification of gene functions, interactions, and pathways3. Identifying the full range...08-27-2024, 04:44 AM
