removed duplicated and trailing whitespace

[pickettbd]

I removed the duplicated and trailing whitespace from index files. In some cases, 2 or more tabs were present between columns. I also removed the trailing whitespace at the end of the lines. Otherwise, the text remains the same.

Issues were fixed with GNU sed like this:
sed -r -i 's,\t+,\t,g' file1 file2 ... fileN
sed -r -i 's,[\t ]+$,,' file1 file2 ... fileN

Here is the list of affected files:

Thanks Brandon - I'll check how those occurred in index generation process.

[chunlinxiao]

For sequence.index files, we intended to have 5 columns for capturing paired reads with their md5s and sample name (column5). For alignment.index file, we intended to have 4 columns for bam and bam.bai with their md5.

All the examples you listed above regarding sequence.index files were not paired reads, thus two empty fields were included there.

For some reason during updating those 4 alignment index files, extra space or tab were introduced, but now have been fixed.

Okay- I think that makes sense. Let me just make sure I understand. You're saying that:

1. The sequence index files should have 5 columns regardless of whether there are paired reads or single reads
2. Alignment index files should have 4 columns.

Is it also safe to assume the following?

3. Columns are tab-delimited for both sequence and alignment index files
4. No spaces or tabs should trail the end of a line

Also- thanks for fixing those 4 alignment index files 😄 🙏

[chunlinxiao]

yeah your assumptions are correct !

Also, please inform us when you find any unusual in index files.

Personally I really appreciate your efforts in helping us to make this resource more valuable.

Glad I can help 😄

If I come across any other things, I'll share my findings in an issue.

Another clarifying question for you: are the bionano alignment files supposed to have only 2 columns (XMAP_CMAP & XMAP_CMAP_MD5)?

[chunlinxiao]

actually Bionano xmap/camp index was an exception for alignment.index, and described in https://ftp-trace.ncbi.nlm.nih.gov/ReferenceSamples/giab/README.ftp_structure:

The format of sequence.index (if no paired data, column 3 and 4 will be empty) as follow:
For fastqs:
FASTQ FASTQ_MD5 PAIRED_FASTQ PAIRED_FASTQ_MD5 NIST_SAMPLE_NAME

For hdf5:
HDF5 HDF5_MD5 NIST_SAMPLE_NAME

For SOLiD xsq:
XSQ XSQ_MD5 NIST_SAMPLE_NAME

For BioNano bnx:
BNX BNX_MD5 NIST_SAMPLE_NAME

The format of alignment.index:
For BAM:
BAM BAM_MD5 BAI BAI_MD5

For BioNano XMAP or CMAP:
XMAP_CMAP XMAP_CMAP_MD5

Many thanks to you Brandon.
