  • Makeblastdb error: file does not exist.

    I just downloaded the blast command line applications and I would like to make a database of a MGEs nucleutides that i downloaded from ACLAME database site in fasta file. It is labeled as mydb.fasta and I have put the file into a bin folder of blast in the path C:\Program Files\NCBI\blast-2.12.0+\bin

    Ive been typing this into the command line:

    cd C:\Program Files\NCBI\blast-2.12.0+\bin to enter in directory

    makeblastdb -in mydb.fasta -dbtype nucl -out DB

    Building a new DB, current time: 09/23/2021 13:48:15 New DB name: C:\Program Files\NCBI\blast-2.12.0+\bin\DB New DB title: mydb.fasta Sequence type: Nucleotide Keep MBits: T Maximum file size: 1000000000B BLAST options error: File mydb.fasta does not exist

    every time i got this error file does not exist. It is probably a simple problem to solve, but I cannot seem to get past it.

    Essential Discoveries and Tools in Epitranscriptomics
    by seqadmin




    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...

    Current Approaches to Protein Sequencing
    by seqadmin


    Proteins are often described as the workhorses of the cell, and identifying their sequences is key to understanding their role in biological processes and disease. Currently, the most common technique used to determine protein sequences is mass spectrometry. While still a valuable tool, mass spectrometry faces several limitations and requires a highly experienced scientist familiar with the equipment to operate it. Additionally, other proteomic methods, like affinity assays, are constrained...
