How much RAM do I need for RNA-seq?

RAM requirements: at least 10 x GenomeSize bytes. For instance, human genome of ~3 GigaBases will require ~30 GigaBytes of RAM. 32GB is recommended for human genome alignments. Sufficient free disk space (>100 GigaBytes) for storing output files.

How many reads needed for RNA-seq?

How many reads should I target per sample? Read depth varies depending on the goals of the RNA-Seq study. Most experiments require 5–200 million reads per sample, depending on organism complexity and size, along with project aims.

How long does it take to analyze RNA-seq data?

The sequencing reactions can take between 1.5 and 12 d to complete, depending on the total read length of the library. Even more recently, Illumina released the MiSeq, a desktop sequencer with lower throughput but faster turnaround (generates ∼30 million paired-end reads in 24 h).

How much does it cost to sequence RNA?

Typical costs for a bulk RNA-seq experiment range from $1000-$2500. Additional analysis or stand alone bioinformatic service costs vary by project complexity and are based on $89/hour rate.

Is 16gb RAM enough for bioinformatics?

The RAM requirements for some bioinformatics analyses like assembly can be quite high (in the hundreds of Gigabytes). Something with an i7 quad-core processor, 16 GB of RAM, and 1TB of storage should do.

Is 8GB RAM enough for bioinformatics?

In bioinformatics, your laptop needs to have a good processing speed. As for the memory, you’re good if your laptop has 8GB of RAM. Some users may be able to do it with just 4Gb of RAM, but we won’t recommend that you run out of memory in a couple of years.

How big is RNA-Seq data?

A typical RNA-seq read file is over 10 Gb. Typically to obtain the raw data, my collaborators send a hard drive to the sequencing facility – courier service is faster than up and down-loading from the computing Cloud! After mapping to the reference, the reads are converted to counts per feature.

What is read depth in RNA-seq?

One of the first considerations for planning an RNA sequencing (RNA-Seq) experiment is the choosing the optimal sequencing depth. As described in our article on NGS coverage calculation, the term sequencing depth describes the total number of reads obtained from a high-throughput sequencing run.

Is RNA-seq reliable?

The advantage of RNA-Seq over microarrays is that it provides an unbiased insight into all transcripts (Zhao et al., 2014). Thus, RNA-Seq is generally reliable for accurately measuring gene expression level changes.

What can I do with RNA-seq data?

Some of the most popular techniques that use RNA-seq are transcriptional profiling, single nucleotide polymorphism (SNP) identification, 3 RNA editing and differential gene expression analysis. This can give researchers vital information about the function of genes.

Why is RNA-Seq so expensive?

Nonetheless, RNA sequencing is still expensive and time-consuming, because it first requires the costly preparation of an entire genomic library — the DNA pool generated from the RNA of cells — while the data itself are also difficult to analyze.
