ok, this might be a dumb question but where did you get the bowtie2 src file? The manual say to look for "the filename that ends in "-src.zip". There is no bowtie....-src.zip file on the bowtie sourceforge site that I can find. Only the one for 0.12.7.Leave a comment:

For mappers that index the genomes, RTGinvestigator/bwa-0.6 are known to work with >4GB genomes. Agile is likely to support long genomes, too. Mappers that index the reads (e.g. maq) may work large genomes if one chromosome is no longer than 2GB.
Supporting >4GB genomes is non-trivial and usually comes at a cost.Last edited by lh3; 11-18-2011, 04:27 PM.Leave a comment:

bowtie2 fun
OK, folks
Who here has used bowtie2-build on a database >4GB in size?
When I try it with the latest Beta3 release with the 64Bit binary (which is supposed to allow databases > 4GB, it spits and dies during bowtie2-build with:
Error: Reference sequence has more than 2^32-1 characters! Please divide the
reference into batches or chunks of about 3.6 billion characters or less each
and index each independently.
Just wondering if anyone has successfully build an index using any releases of bowtie2 on large dbs.

Non-coding RNAs (ncRNAs) do not code for proteins but play important roles in numerous cellular processes including gene silencing, developmental pathways, and more. There are numerous types including microRNA (miRNA), long ncRNA (lncRNA), circular RNA (circRNA), and more. In this article, we discuss innovative ncRNA research and explore recent technological advancements that improve the study of ncRNAs.

Metagenomics has improved the way researchers study microorganisms across diverse environments. Historically, studying microorganisms relied on culturing them in the lab, a method that limits the investigation of many species since most are unculturable1. Metagenomics overcomes these issues by allowing the study of microorganisms regardless of their ability to be cultured or the environments they inhabit. Over time, the field has evolved, especially with the advent...09-23-2024, 06:35 AM -
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.
Jean-Laurent Casanova, M.D., Ph.D., Professor at Rockefeller University, is a leading expert in this crossover between genetics and infectious...09-09-2024, 10:59 AM
