The phrase "a minimum abundance of" is correct and usable in written English.
It can be used when discussing the least amount of something that is present or required in a particular context.
Example: "The study found that there was a minimum abundance of nutrients necessary for plant growth in the soil."
Alternatives: "a basic level of" or "a minimal quantity of".
Nine automatically detected feature pairs (Table S-3) with a minimum abundance of 10 counts were selected for subsequent MS/MS experiments.
Both the native and the U-C precursor ions had to exhibit a minimum abundance of 10 counts in at least three recorded scans for being selected for successive LC-HRMS/MS measurements and evaluation by FragExtract.
To accommodate the fact that de novo assembly is unable to account for T. amboinensis chemoreceptors that yield little to no transcriptional signal (i.e., those that may be present in the genome but are otherwise not discernable), we have limited our quantitative analysis to transcripts that showed a minimum abundance of two RPKM.
Data utilized in the histogram was restricted to miR observed at a minimum abundance ratio level of 5 per thousand miR observed.
The Lactobacillus spp. had a minimum abundance under applied current of 5.9 % and a maximum of 67.0 %, compared to the control case with a minimum of 0.0 % and a maximum of 1.3%% (ignoring t = 0, at which both had greater than 99%% abundance of Lactobacillus spp., identical to the feed).
One limitation of this method is that it requires a minimum abundance and uptake rates of the target group in the sample (Teira et al., 2004).
Hence, only plots containing at least one of these host plant species at a minimum abundance (>5% cover in May 2006) were used for this study (Table S1).
For that reason, the abundance estimates using this method will always result in a minimum abundance.
Before quantitation a second filtering step was performed to retain only those proteins with enough abundance (minimum abundance of 0.001) for a low-biased quantitation [ 90, 91].
Minia was compiled using the make k = 100 option to include higher k-mer sizes and run with a k-mer size of 31 and minimum abundance of 4. Mira (version 3.4.1.1) was run in accurate mode (job=denovo,genome,accurate,solexa SOLEXA SETTINGS GE:tismin=100 tismax=200) on a subset of 20 million reads randomly chosen from library 24 by a custom Python script.
A minimum sRNA abundance of 2 was set with a maximum of 16 genomic hits and a size-range of 18-24.
