Data Import into ggKbase

After the data preparation steps are completed, you will be left with a directory that looks similar to this (note that all files of interest have the common prefix BASE_NAME_scaffold_min1000* ):

> ls

BASE_NAME_scaffold.fa
BASE_NAME_scaffold_min1000.16S.cmsearch

>> Ask Rohan to move the final import files to assembly.d in the project’s directory within /group/banfield/sequences/2020/. This is where they should be imported from.

All the BASE_NAME_scaffold_min1000* files, with their properly formatted names, are used during the ggKbase import steps…

Importance of Sample Metadata

We are trying to pay more attention to metadata associated with each sample. Instead of keeping these details in a spreadsheet, away from the data in ggKbase, we’re incorporating it into the system.  This is an ongoing discussion – if you think you have some metadata that belongs in ggKbase, submit a ticket.

Project Creation

If you have a small number of projects to create and are a member of the Banfield research network, you can create new projects by going here: http://ggkbase.berkeley.edu/projects/new.

Follow the instructions there for filling in the metadata.

If you have many (e.g. >3) new projects to create:

To import your data, download the template below and complete it with your sample information. Save the file as a TSV (in Numbers, go to File > Export To > TSV) and send the completed table to Leylen via Slack.

ggkbase_bulk_upload_template_2025

**NOTE: Exporting as a .tsv from excel messes up the formatting, please use “Numbers” in Mac ideally or Google sheets to fill in your info. If you need a real example TSV import file ask Leylen for it.

(UCBerkeley shared only, so use your .berkeley.edu account.)

To find total basepairs assembled:

On biotite, use sum-bp *min1000.fa

To find total read basepairs:

Find the number of reads in the second line of the idba_ud ‘log’ file. Multiply this number by the read length.

Instructions for TSV Validation Before Sending

1. Run the following command to inspect the TSV:

python /home/leylenm/scripts/ggkInspector.py -t path/to/tsv

Replace path/to/tsv with the actual file path.

 

Note: If you don’t have them, install the necessary packages to be able to run the script:

pip3 install mysql mysql-connector-python pandas

2. If the script detects errors, fix them before sending the file.

•Do not send me the TSV if it still has errors.

•Make all necessary corrections and rerun the script until there are no errors.
