were constructed in this study (Table S1). However, we only recovered 4,958 RNA vOTUs, which accounted for 0.68% of all the viruses in the DOV, and all of them were classified as unknown Riboviria (Fig. S1). Compared with the substantial DNA virus sequence database, the dataset of RN...

filterD()from the next version of FSA (v0.9.0). It will likely be removed by the start of 2022.filterD()was an attempt to streamline the process of usingfilter()(fromdplyr) followed bydroplevels()to remove levels of a factor variable that no longer existed in the filtered data frame...

Further downstream analysis of the results was performed with in-house-developed tools for the extraction of metadata from the mass spectrometry files based on MSFileReader (Thermo Fisher Scientific) and with the R scripting and statistical environment (21) using ggplot (22) for data visualization....
The STRING database was used to construct a PPI network, revealing significant connections between proteins encoded by the common DEGs. To identify hub genes within the network, two algorithms—degree of connectivity and bottleneck—were applied using the “igraph” package (version 2.0.3) in R....
