Error: Sorted input specified, but the file has the following out of order record with a different sort order than the genomeFile

This is caused because my bed file is not sorted numerically using sort. The correct order I needed to input was:

bedtools complement -i

Now, no error exists.
To get corrected.bed, I have sorted numerically in the following way:
cat original.bed | sort -n -k1.11 -nk2,2 >corrected.bed

makeblastdb - Segmentation fault (core dumped)
I had a list of sequence which I wanted to use as NCBI BLAST database. makeblastdb (version 2.7.1+) was throwing me the following error!
Tried the following:
1) Let's remove comma's
2) Now let's try removing brackets in fasta headers
3. Shorten the header - This has worked!!
Appears like makeblastdb has a limit for the length for the headers in fasta. Should take note of it!

BLASTN Error: NCBI C++ Exception
Ran into this error today morning.
Found that incomplete or corrupted database causes this problem. I had two copies of the same NT database, so I ran md5sum for each of the file in the database and found the md5sum of one of the file was not same. (see below)
the long string above is md5sum,file name. - Note the md5sums of the same file are not same.
So just copied the nt.00.nhr file from the archive and blast worked without trouble. If not, you have to download the database again or run makeblastdb again on the fasta sequences.

Connection timed out; no servers could be reached - CentOS - Solved
For some reason, could not connect access internet in CentOS, although my network shows connected. $ nslookup google.com ;; connection timed out; no servers could be reached $ ping www.google.com ping: www.google.com: Name or service not known $ ping 8.8.8.8 From XX.XX.X.X icmp_seq=1 Destination Net Unreachable From XX.XX.X.X icmp_seq=2 Destination Net Unreachable From XX.XX.X.X icmp_seq=3 Destination Net Unreachable From XX.XX.X.X icmp_seq=4 Destination Net Unreachable
then, from an online post, I understand that/etc/sysconfig/network should have following:
$ cat /etc/sysconfig/network
NETWORKING=yes
When I checked my/etc/sysconfig/network, it was empty. Soon, I updated it withNETWORKING=yes GATEWAY=XX.XX.X.X (filled with my IP address)and restarted my system again, which works now without problem!!

Setting up AWS CLI and Downloading S3 Files using command line interface
1. Install the AWS Command Line Interface (CLI) using:
For more details such as upgrade, check the amazon webpage here.
Note: if installation was not successful, reinstall forcefully. Check here
The next step is to configure. AWS requires the following items for this:
(how to find these?)
Now, run the following command and answer the prompts:
3. Copying files from AWS S3 folder to Local Desktop
once this is done, we can start using AWS CLI for the file operations. For example, if it want to copy WBB3097.gz file in my AWS account to my local desktop, which is under "qgen" username and in the folder MIX7341, I do the following
4. List all files in AWS S3 folder
Similarly to list all the files in the MIX7341, we can use the following command
5. Copy multiple files using BASH for loop
Off hand, I had to download multiple files from AWS account. To click each file and download was taking time. So, I just listed the files (step1 below) and used "for loop" in bash to download the files (step2 below).

For more details such as upgrade, check the amazon webpage here.
Note: if installation was not successful, reinstall forcefully. Check here
The next step is to configure. AWS requires the following items for this:
(how to find these?)
- Access key ID
- Secret Access key
- Region name
- Valid output format
Now, run the following command and answer the prompts:
$ aws configure
AWS Access Key ID [None]: <enter the access key> AWS Secret Access Key [None]: <enter the secret access key> Default region name [None]: <enter region> Default output format [None]: <text>
3. Copying files from AWS S3 folder to Local Desktop
once this is done, we can start using AWS CLI for the file operations. For example, if it want to copy WBB3097.gz file in my AWS account to my local desktop, which is under "qgen" username and in the folder MIX7341, I do the following
$ aws s3 cp s3:URI <Local Desktop Location> $ aws s3 cp s3://qgen/MIX7341/WBB3097.gz ~/Desktop/AWS
4. List all files in AWS S3 folder
Similarly to list all the files in the MIX7341, we can use the following command
$ aws s3 ls s3://qgen/MIX7341/ 2018-08-02 11:03:58 459407360 WBB3066.gz 2018-08-02 11:03:01 337848320 WBB3067.gz 2018-08-02 11:02:57 327219200 WBB3068.gz 2018-08-02 11:02:57 298680320 WBB3069.gz 2018-08-02 11:02:57 280514560 WBB3070.gz

We can check aws version as following:
$ aws --version aws-cli/1.15.70 Python/2.7.5 Linux/3.10.0-693.17.1.el7.x86_64 botocore/1.10.69
Thats it ! We can now use AWS CLI to access the buckets in our AWS console account. :)

Converting date to fractional date for BEAST phylogenetic analysis software
While running BEAST, we need to generate an xml with the parameters. When we import the alignment file into BEAUti software and we require the sampling time in fractional years. Here is one way to do that in the excel. Regardless of your date is in any of the formats, the formula would convert that into a fractional year.
=YEAR(A1)+((A1)-DATE(YEAR(A1),1,0))/(DATE(YEAR(A1)+1,1,0)-DATE(YEAR(A1),1,0))
=YEAR(A1)+((A1)-DATE(YEAR(A1),1,0))/(DATE(YEAR(A1)+1,1,0)-DATE(YEAR(A1),1,0))

Merged entries in the non-redundant Nucleotide (nt) database
I ran the following command for to extract a sequence from nt database:
I noticed that this is a merged entry in the 'non-redundant' Nucleotide (nt) database, where two nucleotide sequences which have the same sequence are combined under a single FASTA entry.
When I used the second identifier in the merged entry, blastdbcmd command gave me the same result in return:
$ blastdbcmd -db /mnt/Storage/nt/nt/nt -entry KJ413946.1 | grep '>' >KJ413946.1 Escherichia coli strain ECS01 plasmid pNDM-ECS01, complete sequence >KP900017.1 Raoultella ornithinolytica strain YNKP001 plasmid pYNKP001-NDM, complete sequence
I noticed that this is a merged entry in the 'non-redundant' Nucleotide (nt) database, where two nucleotide sequences which have the same sequence are combined under a single FASTA entry.
When I used the second identifier in the merged entry, blastdbcmd command gave me the same result in return:
$ blastdbcmd -db /mnt/Storage/nt/nt/nt -entry KP900017.1 | grep '>' >KJ413946.1 Escherichia coli strain ECS01 plasmid pNDM-ECS01, complete sequence >KP900017.1 Raoultella ornithinolytica strain YNKP001 plasmid pYNKP001-NDM, complete sequence
Curious to know, I checked if they are the same length. Yes they are of same length (41190).
$ blastdbcmd -db /mnt/Storage/nt/nt/nt -entry KP900017.1 | grep -v '>' | tr -d '\n' | wc 0 1 41190 $ blastdbcmd -db /mnt/Storage/nt/nt/nt -entry KJ413946.1 | grep -v '>' | tr -d '\n' | wc 0 1 41190
Again curious to know, if these two sequences are sharing an exact similarity match, I blasted both of them. And with no surprise, they share 100 % identity. See blast screenshots below:
So, how to sort this out? I need only one annotation instead of multiple for my analysis and do not want the second identifier to confuse my downstream analysis scripts.
By searching around, problem could solved by using "-target_only" option while running the command. I believe this situation might arise in nr database too but switching this on should help to achieve the purpose.
$ blastdbcmd -db /mnt/Storage/nt/nt/nt -entry KJ413946.1 -target_only | grep '>' >KJ413946.1 Escherichia coli strain ECS01 plasmid pNDM-ECS01, complete sequence
