 You can input your a3m format MSA file. For multimer predictions, the a3m file should be compatible with colabfold format.
 
+### Flags
+
+These flags are useful for the predictions.
+
+- **`--amber`** : Use amber for structure refinement (relaxation / energy minimization). To control number of top ranked structures are relaxed set `--num-relax`.
+- **`--templates`** : Use templates from pdb.
+- **`--use-gpu-relax`** : Run amber on NVidia GPU instead of CPU. This feature is only available on a machine with Nvidia GPUs.
+- **`--num-recycle <int>`** : Number of prediction recycles. Increasing recycles can improve the quality but slows down the prediction. Default is `3`. (e.g. `--num-recycle 10`)
+- `--custom-template-path <directory>` : Restrict template files used for `--template` to only those contained in the specified directory. This flag enables us to use non-public pdb files for the prediction. See also https://github.com/sokrypton/ColabFold/issues/177 .
+- `--random-seed <int>` **Changing the seed for the random number generator can result in different structure predictions.** (e.g. `--random-seed 42`)
+- `--num-seeds <int>` Number of seeds to try. Will iterate from range(random_seed, random_seed+num_seeds). (e.g. `--num-seed 5`)
+- `--max-msa` : Defines: `max-seq:max-extra-seq` number of sequences to use (e.g. `--max-msa 512:1024`). `--max-seq` and `--max-extra-seq` arguments are also available if you want to specify separately. This is a reimplementation of the paper of [Sampling alternative conformational states of transporters and receptors with AlphaFold2](https://elifesciences.org/articles/75751) demonstrated by del Alamo *et al*.
+- `--use-dropout` : activate dropouts during inference to sample from uncertainity of the models.
+- `--overwrite-existing-results` : Overwrite the result files.
+- For more information, `colabfold_batch --help`.

 ## How to update
 
 Since [ColabFold](https://github.com/sokrypton/ColabFold) is still a work in progress, your localcolabfold should be also updated frequently to use the latest features. An easy-to-use update script is provided for this purpose.
