# 5.2 Populate the tracking database with the S3 paths for the samples to be processed

**After inputting the sample information, users need to input the location of the sequencing file to process into the tracking database. This can be done using the following command:**

```
function rawurlencode(){echo -n "$1" | perl -pe 's/([^a-zA-Z0-9_.!~*()'\''-])/sprintf("%%%02X", ord($1))/ge' | perl -pe 's/(\W)/sprintf("%%%02X", ord($1))/ge'}
```

```
$  s3='s3://YOUR/DATA/PATH.bam'    ### S3 path for each of the samples to be processed $  seqfile_s3_path=$(rawurlencode $s3)
```

```
curl -sS "http://IP/v1/sample/set-attr/seqfile_s3_uri/${project_id}/${sample_name}/${seqfile_s3_path}"
```

<mark style="color:blue;">`GET`</mark> `http://IP/v1/sample/set-attr/seqfile_s3_uri/${project_id}/${sample_name}/${seqfile_s3_path}`

Add the path of original sequence file from S3.
