Mapping a draft sequence to a finished sequence using MUMmer.

Can anybody tell me why MUMmer is not working?

nucmer --prefix=ref_qry ref.fasta qry.fasta

show-coords -rcl ref_qry.delta > ref_qry.coords

show-aligns ref_qry.delta refname qryname > ref_qry.aligns

I am confused with refname and qryname. What are those ids. The coordinate file shows:

 [S1]     [E1]  |     [S2]     [E2]  |  [LEN 1]  [LEN 2]  |  [% IDY]  |  [LEN R]  [LEN Q]  |  [COV R]  [COV Q]  | [TAGS]
===============================================================================================================================

    1    14175  |   205133   219307  |    14175    14175  |    97.91  |  4004792   636544  |     0.35     2.23  | gi|1122346792|ref|NZ_CP018664.1|  NODE_1_length_636544_cov_49.323596

45796    46499  |   274447   275150  |      704      704  |    99.43  |  4004792   636544  |     0.02     0.11  | gi|1122346792|ref|NZ_CP018664.1|  NODE_1_length_636544_cov_49.323596

What id I can give to this command? also, How to plot that using mummer plot?

mummer

What exactly is not working? It seems MUMmer have performed the alignment just fine.

What should be given in the step given below:

show-aligns ref_qry.delta refname qryname > ref_qry.aligns

What is refname and qryname and how to plot this alignment.

show-aligns ref_qry.delta refname qryname > ref_qry.aligns

I could not understand What is refname and qryname and how to plot this alignment. Please help.

What should be given in the step given below:

show-aligns ref_qry.delta refname qryname > ref_qry.aligns

What is refname and qryname and how to plot this alignment.
