  • CummeRbund error

    Hi all,

    I am just running the cummerbund R script and running into a problem when i make the volcano plots. Its only with the volcano plots and other plots look fine, density and scatter. What am i doing wrong? Below is the output...

    Error in if (nrow(layer_data) == 0) return() : argument is of length zero


    Also is there a way i can change the X axis of the volcano plots so that they all look similar? When i searched around ...I found the code in another thread..So can i switch the scale_y_continuous to scale_x_continuous? or do i just use xlimits= c(-x, x ).

    v<-csVolcano(genes(cuff),'Sample_A','Sample_B')
    v+ scale_y_continuous(limits = c(0, 20))

      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...

      Strategies for Sequencing Challenging Samples
      by seqadmin


      Despite advancements in sequencing platforms and related sample preparation technologies, certain sample types continue to present significant challenges that can compromise sequencing results. Pedro Echave, Senior Manager of the Global Business Segment at Revvity, explained that the success of a sequencing experiment ultimately depends on the amount and integrity of the nucleic acid template (RNA or DNA) obtained from a sample. “The better the quality of the nucleic acid isolated...
