The phrase "all samples and then" is not correct and lacks clarity in written English.
It may be intended to indicate a sequence of actions involving samples, but it requires additional context to be meaningful.
Example: "We will analyze all samples and then proceed to the next phase of the experiment."
Alternatives: "all samples followed by" or "all samples and afterwards".
Images were acquired with MetaVue software using the same exposure time for all samples and then deconvoluted using AutoDeblur software.
RNA integrity was checked by formaldehyde-agarose gel electrophoresis for all samples and then 1 µg of DNase-treated RNA (DNA-free kit, Ambion, Austin,TX) was converted into cDNA using the High-Capacity cDNA Reverse Transcription kit (Applied Biosystems, Foster City, CA).
The PHS test was conducted first for all samples and then separately for each individual population.
For each of these two data sets the PCoA was first performed with all samples, and then excluding the outgroup and the Cerro Zamorano population.
Cell aliquots were harvested at each data point in Figure 2. Cells were diluted to an optical density at 600 nm = 0.1 for all samples and then were subsequently fixed by the addition of 0.25% formaldehyde (final concentration).
It operates similarly to the initial steps of the U-statistic (Abraham et al., 2010; Wilcoxon, 1945), by independently computing the ranks for each gene across all samples and then summing the ranks within each sample.
If more than one quarter had CMT ≥ 3 they were all sampled and then one of the samples was randomly picked at the laboratory and included in the study.
We used GATK's Unified Genotyper to call SNPs simultaneously on all SureSelect samples and then on all TrueSeq samples.
They extracted oxygen from all the samples and then passed it through the spectrometer to find out the proportions of each isotope.
PCA is performed on all NGS samples and then the first component is used to rank regions, which captures the largest proportion of the variance.
The empirical distribution of any given test statistic, such as the χ or DW, is obtained by fitting the model of interest to all bootstrap samples, and then for each fit, calculating the appropriate test statistic.
