@bianchini88 Hi, hopefully I have understood what you have commented.

[bedroesb]

@Arnedeklerk Please check wether all mentioned tools are in the tools and resources list, for example: agrischemas seems not to be present. More info: https://rdmkit.elixir-europe.org/tool_resource_update#the-main-yaml-file

[Arnedeklerk]

My first time trying to contribute here, hopefully now all should be well, @bedroesb

pending #1811

[bedroesb]

@Arnedeklerk thanks a lot for these suggestions, lets bring all changes for this in one branch/pull request. This will be needed for the GitHub Actions and will also improve reviewing (see also my comment in the other PR)

@bedroesb Hi, strange that those counted as duplicate entries, no? Maybe they were meant to be in a different order or something?

[bedroesb]

@Arnedeklerk I agree that this was strange, they were already present on master: https://github.com/elixir-europe/rdmkit/pull/1814/changes but that should not affect the branch here 🤔

[bedroesb]

@NielsGeudens Tagging you to also have a look at this.

[bedroesb]

@Arnedeklerk do you agree with the suggested changes by Federico? If so you can commit them!

[Arnedeklerk]

Looks good, go for it @bedroesb
