How can I find matches between two csv files according to multiple columns using awk/bash?

*Reposted question with no images, removed useless information.

I want to compare File 1 and 2 in two ways:

  • First, match "subject id" in File 2 with "seqnames" in File 1
  • Then, see if File 2's s.start-s.end range overlaps or falls within File 1's start and end range.

If such matches occur, I would like to print out columns 2-23 from File 1, and then every column but #2 (subject id) from File 2 to the right of that.

File 1:

strand  seqnames      start  end    width  [18moreColumns]
1       Ha412HOChr01  1000   10000  9000    ...
2       Ha412HOChr01  19000  21000  2000    ...
3       Ha412HOChr08  2000   11000  9000    ...
4       Ha412HOChr17  92500  94400  1900    ...

File 2:

query id  subject id    % identity  alignment  mismatch  gap open  s.start  s.end  [3 more columns]
XP_02299  Ha412HOChr01  100         335        0         0         2800     3200   ...
XP_02356  Ha412HOChr01  99.86       189        2         1         18900    19800  ...
XP_04271  Ha412HOChr03  98.21       431        4         0         2100     2432   ...
XP_05788  Ha412HOChr08  93.29       38         0         0         7600     8210   ...
XP_06354  Ha412HOChr08  97.89       98         0         0         32100    34980  ...

Output:

seqnames      start  end    width  [18moreColumns]  query id  % identity  alignment  mismatch  gap open  s.start  s.end  [3 more columns]
Ha412HOChr01  1000   10000  9000    ...             XP_02299  100         335        0         0         2800     3200   ...
Ha412HOChr01  19000  21000  2000    ...             XP_02356  99.86       189        2         1         18900    19800  ...
Ha412HOChr08  2000   11000  9000    ...             XP_05788  93.29       38         0         0         7600     8210   ...

using sqldf in R:

> sqldf('select * from df1 join df2 on df1.seqnames= df2.subject_id where 
+     df2.s_start between df1.start and df1.end OR
+     df2.s_end between df1.start and df1.end')

using fuzzyjoin in R (default inner_join):

> names(df2)[c(2,7,8)]=c("seqnames","start","end")
> genome_join(df1, df2, by=c("seqnames","start","end"))
  strand   seqnames.x start.x end.x width query_id   seqnames.y x_identity alignment mismatch gap_open start.y end.y

Please do not use special characters in column headers (%, space, dot etc).

This is purely informatics based question, rather bioinformatics!

When in doubt with tabular data, pandas is best used.

You can use intersectbed for this purpose. It can work on BAM/BED/GFF/VCF formats. However if you don't have these formats as can be seen by file shared by you, then try to make files in a way that you have IDs to be compared in 1st column and start, end in 2nd and 3rd column and rest information in following columns.
