If it can help someone in the future, we can get this type of information on NCBI: ftp://ftp.ncbi.nlm.nih.gov/genomes/g...ate_mammalian/
In *_report.txt files, for each contigs, there is assembled-molecule / unlocalized-scaffold / unplaced-scaffold / novel-patch / fix-patch or alt-scaffold.

Extracting alternate loci from fasta genome
Dear all,
I downloaded full reference fasta genomes for hg19, mm9 and mm10 from gencode. They include reference chromosomes, scaffolds, assembly patches and haplotypes.
For a specific purpose, I want to remove haplotypes.
I did not manage to find a description of the nomenclature used for the contigs in fasta file.
In the hg19 reference genome I use, there are 297 contigs. One can see for example:
I would like to know how many of them are haplotypes and which ones are they.>chr1 1
>chr2 2
...
>chrM MT
>GL877870.2 HG1007_PATCH
>GL877872.1 HG1032_PATCH
...
>GL383545.1 HSCHR10_1_CTG2 <- is it an "unlocalized sequence" ?
>GL383546.1 HSCHR10_1_CTG5
...
>GL000191.1 GL000191.1
>hg19GL000192.1 GL000192.1
Is there a way to get this information?
Thank you in advance for your help.

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
