First, the basic total number of reads at a given position is the number of reads with a particular base plus the number of reads with that a deletion at that given position. Note that deletions of two bases and one base would be counted separately. Insertions are not counted in this total, which is used to calculate the proportion of occurrences of each individual base and deletion. For position 4 above, the reference base is G, and there are 2 occurrences of it along with one each of mismatching bases A and C. Also, there is on 1-base deletion. So there are a total of 5 matches/mismatches/deletions, and the proportions for each base are either 1/5 = 0.20 or 2/5 = 0.40, and for the deletion it is 1/5 = 0.20. Insertions are slightly more complicated. Each insertion is regarded individually, and the total number of occurrences of that insertion is divided by the sum of the number of its occurrences and the b asic total. So for position 5, there are a total of 5 matches/mismatches/deletions, and two insertions that each occur once, so each has a insertion has a proportion of 1/6 = 0.17. + +The DELPROP or INSPROP needs to be greater than the threshold frequency specified by the user. + +The output varies for deletions and insertions, though for both, the first three columns are chromosome, start position, and end position. + +Columns in the deletions file:: + + Column Description + ---------------------------- ------------------------------------------------------------------------------------ + 1 Chrom Chromosome + 2 Start Starting position + 3 End Ending position + 4 Number of Deleted Base(s) The number of bases deleted at Start position + 5 Frequency Percentage Frequency of this exact deletion (2 and 1 are mutually exclusive), as percentage (%) + +Columns in the insertions file:: + + Column Description + -------------------------- ------------------------------------------------------------------------------------------------------------- + 1 Chrom Chromosome + 2 Start Starting position + 3 End Ending position (always Start + 1 for insertions) + 4 Inserted Base(s) The exact base(s) inserted at Start position + 5 Freq.

Currently it can handle SAM with alignments that have only one insertion or one deletion, and will skip that alignment if it encounters one with more than one indel. It matches CIGAR strings (column 6 in the SAM file) like 5M3I5M or 4M2D10M, so there must be a match or mismatch of sufficient length on either side of the indel. + +----- + +**Example** + +Suppose you have the following:: + + r770 89 ref 116 37 17M1I5M = 72131356 0 CACACTGTGACAGACAGCGCAGC 00/02!!0//1200210AA44/1 XT:A:U CM:i:2 SM:i:37 AM:i:0 X0:i:1 X1:i:0 XM:i:1 XO:i:1 XG:i:1 MD:Z:22 + r770 181 ref 116 0 24M = 72131356 0 TTGGTGCGCGCGGTTGAGGGTTGG $$(#%%#$%#%####$%%##$### + r1945 177 ref 41710908 0 23M 190342418 181247988 0 AGAGAGAGAGAGAGAGAGAGAGA SQQWZYURVYWX]]YXTSY]]ZM XT:A:R CM:i:0 SM:i:0 AM:i:0 X0:i:163148 XM:i:0 XO:i:0 XG:i:0 MD:Z:23 + r3671 117 ref 190342418 0 24M = 190342418 0 CTGGCGTTCTCGGCGTGGATGGGT #####$$##$#%#%%###%$#$## + r3671 153 ref 190342418 37 16M1I6M = 190342418 0 TCTAACTTAGCCTCATAATAGCT /&lt;&lt;!"0///////00/!!0121/ XT:A:U CM:i:2 SM:i:37 AM:i:0 X0:i:1 X1:i:0 XM:i:1 XO:i:1 XG:i:1 MD:Z:22 + r3824 117 ref 80324999 0 24M = 80324999 0 TCCAGTCGCGTTGTTAGGTTCGGA #$#$$$#####%##%%###**#+/ + r3824 153 ref 80324999 37 8M1I14M = 80324999 0 TTTAGCCCGAAATGCCTAGAGCA 4;6//11!"11100110////00 XT:A:U CM:i:2 SM:i:37 AM:i:0 X0:i:1 X1:i:0 XM:i:1 XO:i:1 XG:i:1 MD:Z:22 + r4795 81 ref 26739130 0 23M 57401793 57401793 0 TGGCATTCCTGTAGGCAGAGAGG AZWWZS]!"QNXZ]VQ]]]/2]] XT:A:R CM:i:2 SM:i:0 AM:i:0 X0:i:3 X1:i:0 XM:i:2 XO:i:0 XG:i:0 MD:Z:23 + r4795 161 ref 57401793 37 23M 26739130 26739130 0 GATCACCCAGGTGATGTAACTCC ]WV]]]]WW]]]]]]]]]]PU]] XT:A:U CM:i:0 SM:i:37 AM:i:0 X0:i:1 X1:i:0 XM:i:0 XO:i:0 XG:i:0 MD:Z:23 + r4800 16 ref 241 255 15M1D8M = 0 0 CGTGGCCGGCGGGCCGAAGGCAT IIIIIIIIIICCCCIII?IIIII XT:A:U CM:i:2 SM:i:37 AM:i:0 X0:i:1 X1:i:0 XM:i:1 XO:i:1 XG:i:1 MD:Z:22 + r5377 170 ref 59090793 37 23M 26739130 26739130 0 TATCAATAAGGTGATGTAACTCG ]WV]ABAWW]]]]]P]P//GU]] XT:A:U CM:i:0 SM:i:37 AM:i:0 X0:i:1 X1:i:0 XM:i:0 XO:i:0 XG:i:0 MD:Z:23 + r5612 151 ref 190342418 37 19M1I3M = 190342418 0 TCTAACTTAGCCTCATAATAGCT /&lt;&lt;!"0/4//7//00/BC0121/ XT:A:U CM:i:2 SM:i:37 AM:i:0 X0:i:1 X1:i:0 XM:i:1 XO:i:1 XG:i:1 MD:Z:22 + + +To select only alignments with indels, you need to determine the minimum quality you want the adjacent bases to have, as well as the number of adjacent bases to check.
