  • Problem about splicing.diff from cuffdiff

    Hi,
    This problem has puzzled me one week long!
    I followed the workflow:Tophat - Cufflinks - Cuffmerge - Cuffdiff,and everything is OK except the splicing.diff file generated by cuffdiff. After running Cuffdiff, it print "Performed 0 splicing tests", and splicing.diff file is filled up with LOWDATA and NOTEST without even one OK. I used merged.gtf as input, which has tss_id and p_id. And I also tried to use combined.gtf from Cuffcompare as input, but the result was the same. Can anyone help me?

    Here is my command:
    1).cuffmerge -o ./merged_asm/ -g genes.gtf -s genome.fa -p 8 assemblies.txt
    2).cuffdiff -o ./diff_asm/ -b ./genome.fa -p 8 -L L1,L2,L3 -u ./merged_asm/merged.gtf ./Sample_out/accepted_hits.bam ./4h_out/accepted_hits.bam ./S48h12_out/accepted_hits.bam

    Then is some lines of my merged.gtf
    Code:
    PHYCAscaffold_1	Cufflinks	exon	41144	42265	.	+	.	gene_id "XLOC_000001"; transcript_id "TCONS_00000001"; exon_number "1"; oId "transcriptId502542"; nearest_ref "proteinId502542"; class_code "o"; tss_id "TSS1";
    PHYCAscaffold_1	Cufflinks	exon	41195	41689	.	+	.	gene_id "XLOC_000001"; transcript_id "TCONS_00000002"; exon_number "1"; oId "proteinId502542"; contained_in "TCONS_00000001"; nearest_ref "proteinId502542"; class_code "="; tss_id "TSS1"; p_id "P1";
    PHYCAscaffold_1	Cufflinks	exon	42789	45015	.	+	.	gene_id "XLOC_000002"; transcript_id "TCONS_00000003"; exon_number "1"; oId "transcriptId502544"; nearest_ref "proteinId502544"; class_code "="; tss_id "TSS2"; p_id "P2";

    Essential Discoveries and Tools in Epitranscriptomics
    by seqadmin




    The field of epigenetics has traditionally concentrated more on DNA and how changes like methylation and phosphorylation of histones impact gene expression and regulation. However, our increased understanding of RNA modifications and their importance in cellular processes has led to a rise in epitranscriptomics research. “Epitranscriptomics brings together the concepts of epigenetics and gene expression,” explained Adrien Leger, PhD, Principal Research Scientist...

    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...
