Hi,
How big is the bam file? It looks GIREMI can't calculate the MI value.

I'm running GIREMI with a list of 2,233 locations, with the first 10 lines as follows:

GIREMI failed to run the R script, and reviewing the intermediate output, it looks like samtools was able to do its job as the allelic depths were counted corrected, but the stats were strange. ifRNAE doesn't exist, the GLM stats are all zero, and while raw MI looks fine, ifMI, pvalue_MI, and allelic ratio were off:

I would appreciate any assistance.
PS: I can confirm the chromosome names are fine, and since I used the same index files for GATK, I take that to mean it wasn't corrupted.

1,179,375kb. This is the default bamout
from GATK, of which I start to wonder if it has dropped too much reads. There're several flags in GATK of which I can obtain a more comprehensive set of reads; I may have to play with them.
I'm convinced, however, that if the location list used in GIREMI originates from HaplotypeCaller or MuTect2, then it must be some kind of GATK bamout from the same run that should be used as the BAM as well.
Hi Qing,
Do you think a .bam with 51,996,757 reads (as counted by samtools view -c
) has enough reads for GIREMI?
Hi Qing,
I have just re-ran GIREMI with a fresh more "conventional" BAM but with the same list. This time the situation seems to have improved in that the the mi and if_mi fields seems to be calculated correctly, but the pvalue of MI (mip) in the file and the mean and SDs of MI emitted on the screen are still off. mip is either 0 or -1, and both meanMI and sdMI are -nan.
I have attached the output of the C code for your reference. SNPiR_1112961-Tumor.UC.GIREMI.results.txt
Hi John,
I found the nucleotide ratios of many variants are very high 0.98~1. I believed there are many homozygous SNV in your list that might affect the calculation. Please use more strict filters to remove these SNVs and try again. Thanks.

Sorry for the delay; I had other projects to handle.
I have further filtered the input to limit it to SNPs that have alt allelic fraction between (and including) 0.1-0.9 from both UnifiedGenotyper and SNPiR. It comes out the same--mip are either -1 or 0.
The list and the output by the C code attached. The coordinates are from GRCh38, primary chromosomes only, GENCODE version.

Hi John,
I found there are no any known SNP in your list.

@zhqingit: Yes, I have filtered away dbSNP positions beforehand. Are those required for GIREMI calculations?
Yes, giremi needs these known SNP information to create the MI distribution.

@zhqingit: Spiking in dbSNP variants does complete the program. Thanks! Closing ticket
