Comment: C: relationship between relative abundance and relative activity
... I think that is something I am struggling with too. I think what I want to get at is to figure out which organism is transcribing the most, i.e most viable? ...

relationship between relative abundance and relative activity
... Hello, I have a bunch of meta-transcriptomics data and I would like to identify which organism is the most active. I plan to calculate TPM/RPKM for each organism and the figure out the "most-active" organism that way. However, I find that this method is over-simplified as I am not taking into accoun ...

how to speed up cdhit clustering?
... I'm trying to run CDHIT to cluster ~250M of cds at nucleotide/protein levels. These are mostly NR-like sequences from NCBI. According to the paper it takes ~ 140 mins to cluster 4M seqs with 8 core. When I run the job, it took > 12 hours to process 1M seqs. I've tried increasing the #cpu to 24 bu ...

Comment: C: how to concatenate contigs from repseq?
... Absolutely! Let's say I want to combine NZ_LNUL01000001:NZ_LNUL01000133 into one whole genome sequences. These are scaffolds from a whole genome seq project on NCBI and are stored in different accessionId's. I would like to combine all these scaffolds (sometimes contigs for some other species) so th ...

tools/resources on mixed-integer programming
... Hi there! Here's the problem I'm trying to solve: Given a pool of gene ID and their read counts -- some genes are unique to one particular species while some are shared--what is the most likely combination of species that can be present in the sample and how to calculate their relative abundance? ...

taxa identification using signature vs alignment to refseq
... Has anyone tried and compared the taxa identified using both signatures and reference sequences? I seem to identify much more taxa from the refseq with little overlap with what i identified from signatures. In this case, which results should i trust more? ...

finding secondary taxid using ete3 ncbiTaxa
... Hello, I'm trying to using ete3's ncbitaxa to get species-to-genus taxid's. I noticed that there are some taxid that aren't found (e.g.1913078 or 1283312). When checking ncbi website, I notice that they are secondary taxid. Is there anyway that I can still find the genus id for these secondary taxid ...

difference between mapq=0 and samtools flag 0x900
... Hello, I am comparing the # of uniquely mapped reads from the same fastq (illumina paired end) to 2 reference sequences using BWA-MEM. I expect mapping to one of the reference sequences (let's call it ref A) to be have many multi-mappers and mapping the other (ref B) to be more unique. Ref A has ma ...
